With both electricity and hydrogen, however, the key question is a what fuel is used to produce it. Electricity produced from renewable sources such as solar, wind and biomass should be encouraged and expanded rapidly. Hydrogen gas for use in fuel cells should be focused upon as the fuel of the future. The fuel cell is like a battery with the fuel attached. If you run hydrogen gas through a fuel cell it chemically produces electricity and doesn't need recharging.
Fuel cells can power a car with virtually no pollution.
They can be built in stacks as large or small as needed to allow planners to accurately meet actual demand. Fuel cells produce heat as well as electricity making them excellent candidates for generating power and providing heat at office buildings, hospitals, hotels and factories or running electric motors in cars, vans, buses and trucks. Facilities can add capacity in almost infinite increments as needed. Technical Information Several kinds of fuel cells are being developed, each distinguished by the particular type of electrolyte they use. Chemical reactions within the cell produce either hydrogen or oxygen bearing ions at one of the two electrodes.
