Using Hydrogen Fuel

Addresses the proper codes, standards, monitoring techniques, and safety designs needed to effectively use hydrogen fuel... 

Wal-Mart has purchased hydrogen fuel cell-powered forklifts for its main warehouse. In addition, the U.S. Postal Service has some vehicles that use hydrogen fuel cells. Fuel cell vehicles are also being used in other countries. In 2009,... 

Hydrogen fuel is made from the most plentiful element in the universe. The actual chemical reaction that forms the fuel results in zero toxic waste. The only waste that is made is water, from which even more hydrogen fuel can be made. This is great news for the environment because it helps to limit the amount of carbon dioxide in the atmosphere. Looking at all these facts, it would seem that there could not possibly be a downside to using hydrogen fuel—but there are drawbacks. 

Phase II — 2000-2001, demonstrate cars and buses using hydrogen fuel ... 

Volkswagen/Volvo Produced a zero-emission vehicle called the Bora HyMotion, based on the Jetta, using hydrogen fuel cells. Also planning a methanol-fuel PEM hybrid "Golf"-t) e car. 

Suppose that you are working with a firm that is using hydrogen fuel cells to power satellites. The satellite requires 4.0 x 10 kj of energy during its useful lifetime to stabilize its orbit. Describe how you would determine the mass of hydrogen you would need in your fuel cells for this particular satellite. 

The potential short-supply of petroleum-based fuels has led to activities by NASA to establish technical characteristics of air transportation systems that would use hydrogen-fueled aircraft. These activities cover sources and production of liquid hydrogen, aircraft configurations, and air terminal modifications, as affected by the introduction of liquid-hydrogen-fueled aircraft. ... 

High-temperature fuel cells using hydrogen fuel offer optimum performance irrespective of current density in terms of moderately higher efficiency, reliability, and operational costs. In addition, methane does not participate directly in the electrochemical reaction. Both methanol and methane yield poor performance when the... 

Figure 7.9 The anode and the cathode reaction for a molten carbonate fuel cell using hydrogen fuel. Note that the product water is at the anode, and that both carbon dioxide and oxygen need to be supplied to the cathode.
