How does a fuel cell work?



A fuel cell is fed hydrogen and air and puts out electricity, heat, and water. The hydrogen gas going in gets split into separate protons and electrons by a catalyst, and the protons travel through a membrane that doesn't let the electrons through. The electrons must find another way, such as through a wire that is provided. The electrons traveling through the wire to meet up with the protons make an electrical current, which does work.The batteries in hybrids are recharged by driving them around in thunderstorms and getting hit by lightning. If the outside temperature falls below 0 degrees F., your hybrid will shatter into a million pieces.

What will happen to all the water put into the air? Will the climate be changed?

What is the difference between HYDROGEN and HYDROZINE? We used HYDROZINE for fuel cells in 1965 at Allis-Chalmers. What is the difference between hydrogen combustion, and fuel cell technology? Are they the same thing? It is very hard to find information on hydrogen combustion, but relatively easy to learn about fuel cells.Fuel cells convert chemical energy into electrical energy without combustion via a chemical reaction. Fuel cells combine hydrogen and oxygen converting them into water. The hydrogen used for conversion into electrical current is actually a by-product of manufacturing at Dow.

What California companies are working on development and marketing of hydrogen and fuel cells?

The California Air Resources Board has compiled the "California Hydrogen and Fuel Cell Guide" - a listing of "companies and organizations working to facilitate the development and deployment of hydrogen and fuel cell technologies in the State of California." To view the guide online, click here.Some HICE (Hydrogen Internal Combustion Engine) vehicles are available today. Fuel cell vehicles will be available later.

Yeah, that was a Massachusetts Supreme Court decision. How'd ya guess?

The batteries in hybrids are recharged by driving them around in thunderstorms and getting hit by lightning. If the outside temperature falls below 0 degrees F., your hybrid will shatter into a million pieces. However, like the T-1000, it can re-assemble itself after it warms up. The next advancement in automotive technology - hydrogen fuel-cell powered cars - will hit the market in 10 to 20 years. Or a week after you finally buy a hybrid for yourself, whichever comes first.I am planning on going on a California tour, educating students about Kids 4 Hydrogen and the hydrogen economy. By presenting the Honda FCX, I will educate students about hydrogen fuel cell cars and how the students can contribute to their future now. This will ensure that kids don't expect ro rely on nuclear or coal for energy production.

Doesn't it take energy to make hydrogen? Is it worth doing?

Like all fuels, it takes energy to produce hydrogen and deliver it to a vehicle. The amount of energy required depends on how the hydrogen is madesome methods require more energy than others. While it may take more energy to produce and deliver hydrogen than it takes to produce and deliver gasoline or natural gas, the hydrogen fuel is used more efficiently in the fuel cell vehicle.Generally speaking, fuel cells use molecular hydrogen as their fuel and oxygen from the air to produce electricity.

CAN HYDROGEN BE USED AS A FUEL?

Because hydrogen is always bound up with something else, it always takes energy to bust it loose. Because of this hydrogen is not a good fuel. It can be thought of as a storage medium for energy. Using solar or wind power to bust hydrogen loose from water can be looked at as "storing" the energy from the sun or wind "in" the hydrogen. Then we can ship the hydrogen around. Its almost as if the hydrogen is a battery we are using to store up energy to be used later.
