Question

How do Hydrogen fuel cells work?

Answer 1

In a hydrogen fuel cell, there are two chambers separated by a very thin membrane.  One chamber contains oxygen, the other contains hydrogen.  A catalyst causes the hydrogen to lose its electron and phase through the barrier to the oxygen chamber as a naked proton.  The electron is directed along a circuit where its energy may be used to drive a motor or for other purposes.  Two electrons join two protons and an oxygen on the other side of the membrane after being used in the circuit to create a water molecule, which is then expelled as exaust.  I believe energy from the reaction producing the water is used to strip more hydrogen ions, but the energy to do work from a hydrogen cell is based on the electric current produced by electrons from the hydrogens.

Answer 2

I don't know maybe it's because you're a f*g.

Answer 3

There are two ways one as previously stated the other is doing the process in reverse .

both ways require a great deal of electricity.
