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.
