or iron-phosphate batteries that can be recharged from central stations prior to beginning each route or by hydrogen-powered fuel cells.

and wind power to charge their batteries or produce hydrogen to power fuel cells. Moreover, as Ie previously mentioned, driving on electricity is compared cheaper to driving on oil.

A previous example of this was the National Fuel cell Bus Program, which invested in the research, development and testing of alternative fuels and related equipment,

and deployment projects to reduce the cost of fuel cells for transit use. In the push for no emissions buses, a few benefits are seen as being possible.

and the China Automotive technology and Research center will work together to help speed the commercialization of plug-in and fuel cell electric cars in China and the U s. under an agreement signed Sept. 6 in Tianjin, China.

#Hybrid#dots#offer cheaper way to run fuel cells Last year chemist James Tour made graphene quantum dots from coal.

The result is a hybrid material that could make it much cheaper to generate energy with fuel cells.

So it s a superb hybridization. he material outperformed commercial platinum/carbon hybrids commonly found in fuel cells.

The hydrogen gas could power fuel cells in zero-emissions vehicles. The battery sends an electric current through two electrodes that split liquid water into hydrogen and oxygen gas.

Fuel cell technology is essentially water splitting in reverse. A fuel cell combines stored hydrogen gas with oxygen from the air to produce electricity

which powers the car. The only byproduct is water unlike gasoline combustion which emits carbon dioxide a greenhouse gas.

In 2015 American consumers will finally be able to purchase fuel cell cars from Toyota and other manufacturers.

The new battery is based on a redox flow designimilar in design to a fuel cell, with two tanks of electroactive materials dissolved in water.

These fuel cells do not harvest electricity as an output. Rather, they use a small electrical input platform to generate hydrogen and increase the MEC efficiency even more.

#Toyota opens fuel cell patents to drive hydrogen society Toyota is serious about hydrogen fuel cell technology.

500 fuel cell patents and provide royalty-free licenses to other automakers and entities. Upon walking into Toyota's CES press conference, the shimmering Mirai under the hard conference room lighting suggested that it might just be a rehashing of the details we already learned at November's LA Auto Show.

"The approximately 5, 680 total global patents break down into roughly 3, 350 fuel cell system software control patents, 1,

970 fuel cell stack-related patents, 290 high-pressure hydrogen tank patents, and 70 hydrogen production and supply patents.

They will be made available to fuel cell vehicle manufacturers, fuel cell parts suppliers, and hydrogen fueling station companies through an initial market introduction period that Toyota expects to run until 2020.

It opens unique possibilities for 3d imaging and exact modeling of geological materials in oil and gas exploration, composite materials, fuel cells and electronic assemblies.

Panasonic Eco Ideas House, with solar, a fuel cell, battery backup and a plug-in Toyota prius, has stood long next to a company headquarters in Tokyo,

potentially delivering hydrogen for fuel cells in mobile phones, computers or even cars. Edman Tsang, a chemist at the University of Oxford, UK, who also works on storing hydrogen in liquids including methanol2,

That means that it may be possible to combine a methanol-hydrogen reaction with a fuel cell that guzzles up the gas to produce electricity.

hydrogen fuel cells are twice as efficient as fuel cells that directly run on methanol, for instance. Not everyone agrees with Beller and Tsang.

#Cool new material could make fuel cells cheaper It not enough for a new alternative energy technology to work.

That been a high hurdle for devices called solid oxide fuel cells (SOFCS) that convert fuelsuch as methane and hydrogenirectly to electricity without burning them.

Commercial devices, by contrast, work by wiring many such devices together into what known as a fuel cell tackthat generates more power.

If future BZY-based SOFC stacks work as well as the individual devices, then it could finally produce the tipping point the fuel cell industry has been looking for n

because other energy storage technologies such as fuel cells, batteries, and flywheels tend to be less efficient, or simply too complex to be reduced practical

Published in the journal Nature the discovery could revolutionize fuel cells and other hydrogen-based technologies as they require a barrier that only allow protons-hydrogen atoms stripped off their electrons-to pass through.

which are at the heart of modern fuel cell technology. Fuel cells use oxygen and hydrogen as a fuel and convert the input chemical energy directly into electricity.

Without membranes that allow an exclusive flow of protons but prevent other species to pass through this technology would not exist.

This can boost competitiveness of fuel cells. The Manchester group also demonstrated that their one-atom-thick membranes can be used to extract hydrogen from a humid atmosphere.

They hypothesise that such harvesting can be combined together with fuel cells to create a mobile electric generator that is fuelled simply by hydrogen present in air.

This hydrogen can then be burned in a fuel cell. We worked with small membranes and the achieved flow of hydrogen is of course tiny so far.

Because graphene can be produced these days in square metre sheets we hope that it will find its way to commercial fuel cells sooner rather than later r

This approach to growing nanomaterials will improve the efficiency of various devices including solar cells and fuel cells.

Manufacturers will be able to optimize the design to a desired electrochemical behavior for a battery or fuel cell, for example.

#Electric compressor could double output of hydrogen fuel cells Fuel cells require a constant source of oxygen to sustain the chemical reaction that they use to release positively charged hydrogen ions.

This allows the motor to be powered directly by the fuel cell without the use of an intermediate voltage regulator.

Fuel cell systems represent a promising alternative for low carbon emission energy production. Traditional fuel cells are limited however by the need of efficient catalysts to drive the chemical reactions involved in the fuel cell.

Historically platinum and its alloys have frequently been used as anodic and cathodic catalysts in fuel cells

but the high cost of platinum due to its low abundance motivates researchers to find efficient catalysts based on earth-abundant elements.

Arizona State university and Xiamen University in China have developed a new fabrication method that minimizes the need for expensive metal to induce catalytic activity in fuel cell applications.

When these nanocage structures are used in fuel cell electrodes, platinum's utilization efficiency can be increased by a factor of seven,

which could affect the economic viability of the fuel cells. e can get the catalytic activity we need by using only a small fraction of the platinum that had been required before,

However, due to its high cost, the use of low-temperature fuel cells in automobile and home applications has been limited.

The research is focused mainly on reducing the expense of cathodes used in fuel cells that power homes and automobiles.

The oxygen-reduction reaction occurring at the cathode in the fuel cell requires platinum in substantial quantities.

The hollow shells could result in economically beneficial automotive and home fuel cells by minimizing the amount of platinum by up to a factor of seven.

600 fuel cell patentsavailable through 2020 to carmakers who produce and sell fuel cell vehicles, and to parts suppliers and companies interested in building and operating fueling stations,

The carmaker hopes the move will spur worldwide development and innovation in fuel cell technologies. It comes on the heels of a similar decision by billionaire entrepreneur Elon musk to make the patents of his electric car company

Companies that make fuel cell busses and industrial equipment can also receive the patents, and requests from nontransportation companies will be evaluated on a case-by-case basis,

Fuel cell vehicle-related patents will be available royalty-free until the end of 2020, while hydrogen-production and supply patents will remain free indefinitely.

Toyota also encouraged other companies to share their fuel cell patents. Carter said his company provided substantial funding for the development of hydrogen fueling infrastructure in California and the northeastern United states. In May 2014

#Researchers synthesize new thin-film material for use in fuel cells: Article in the journal APL Materials shows how to grow Bi2pt2o7 pyrochlore, potentially a more effective cathode for future fuel cells Abstract:

Researchers from Cornell University have synthesized a new thin-film catalyst for use in fuel cells. In a paper published March 10 in the journal APL Materials, from AIP Publishing, the team reports the first-ever epitaxial thin-film growth of Bi2pt2o7 pyrochlore,

which could act as a more effective cathode--a fundamental electrode component of fuel cells from which positive current flows through an external circuit delivering electric power."

"Up to now, research on oxygen catalysts in thin film form for clean energy applications has been focused on the perovskite-structured oxides

"The much less studied cubic pyrochlore structure is an appealing alternative to perovskites for such applications as fuel cell cathodes."

Epitaxial thin films can actually act as more efficient fuel cell catalysts than nanocrystalline powder, but growing Bi2pt2o7 directly as a film requires oxidizing the platinum metal--a challenging step.

thought to be one of the most promising oxide catalysts for fuel cell applications, "said Gutierrez-Llorente.

The cathode of a solid oxide fuel cell electrochemically reduces oxygen. Bi2pto7's oxygen-deficient structure makes it an ideal catalyst for the process.

Synthesizing the material as a thin film instead of as a bulk powder opens up new possibilities for fuel cell technology."
