How does a hydrogen powered car work?
Introduction As the world’s resources are being depleted and pollution is increasing, new, cleaner and more efficient sources of energy are increasingly sought. Automobiles are a major concern because of pollutants in their exhaust and rising costs of oil, so alternative fuel sources are being considered. One such alternative being considered is hydrogen. Hydrogen powered cars are just like gasoline cars on the outside and drive the same but the engine is powered by hydrogen gas fuel cell instead of gasoline. This fuel cell produces electricity through a direct electrochemical reaction in which hydrogen (H2) and oxygen (O2) from the air are combined and convert it into electricity, which is a clean alternative to gasoline. The only emission is water vapor, so the carbon dioxide emissions of gasoline powered cars are no longer a factor contributing to pollution. Hydrogen is an easy to find resource that greatly reduces our dependence on foreign and domestic oil. The efficiency of hydrog
