cells work like a battery. There are two electrodes in a fuel cell. Oxygen passes over one, and hydrogen passes over
the other. This creates electricity, water, and heat.
Hydrogen is fed into the anode, and oxygen goes into the cathode. The hydrogen atom splits into an electron
and proton, and they both go on separate paths to a cathode. The proton goes through an electrolyte.
The electron produces a separate current, and meets up with the proton in the cathode. When they get to the
cathode they turn back into hydrogen, and mix with the oxygen. When the mix you get H2O or water. This is
a cell, and they produce a small voltage. They get arranged with other fuel cells, and create enough electricity to
power an object.
