The answer to that one is to use a renewable energy source such as solar
wind generated electricity to produce the hydrogen by electrolysis ofwater.
Initially, this might seem silly. Why not just use the solar or windHi Folks,
produced electricity directly. However, hydrogen provides a way to store
the energy and use it as needed in certain applications such as motor
vehicles. Using a hydrogen fuel cell in an electric vehicle provides much
greater range than storage batteries.

If you use pure hydrogen as the fuel, the cell should last pretty muchmy
indefinitely. If you use natural gas or other hydrocarbon based fuel,
guess is that the electrodes will become contaminated eventually andthe
cell will stop working.
TX, Mark, but this gives rise to my question re renewability: I am
to stipulate that there is a infinite supply of O2 -- assuming that we
cutting down every tree in the galaxy -- but what is the renewable
