A fuel cell generates electricity from continuously
supplied streams of fuel and oxidant.
The two streams do not mix or burn but produce electricity
by electrochemical reactions similar to a conventional
battery.
The details of the chemical reactions depend on the
type of fuel cell, but in all types an electrically
charged ion is transferred through an electrolyte which
physically separates the fuel and oxidant streams.
The fuel cell provides an elegant means of converting
the chemical energy of the fuel directly into electrical
energy.
