Fuel cell

 

An electrical cell that converts the intrinsic chemical free energy of a fuel into direct-current electrical energy in a continuous catalytic process. Fuel cells extract the chemical energy bound in fuel and, in combination with air as an oxidant, transform it into electricity. Researchers are hoping to develop fuel cells that could take the place of combustion engines, thereby reducing the world dependence on fossil fuels.

An electrochemical device which produces electricity and heat from a fuel (hydrogen and oxygen) without combustion. Basically, a fuel cell can be considered as an inverse electrolysis. Hydrogen and oxygen are reassociated to water using a catalytic process. Fuel cells can be used in electrical powered cars. One problem of fuel cells is the handling and storage of hydrogen. Nanotubes a promising candidates for a future hydrogen storage.
