Uh, so tell me, how does the fuel cell drive the vehicle sans electric motor?

From the hydrogen in the tank?

Fuel cell vehicles produce no pollution by running on the power of the chemical reaction when hydrogen stored in a tank combines with oxygen in the air to produce water.

I feel like the ignorant one now, I thought people generally knew what a fuel cell was. My bad. (No seriously, I'm not being ironic or snarky as I was in my original post.) From the Wikipedia entry on fuel cells:

A fuel cell is an electrochemical conversion device. It produces electricity from various external quantities of fuel (on the anode side) and an oxidant (on the cathode side). These react in the presence of an electrolyte. Generally, the reactants flow in and reaction products flow out while the electrolyte remains in the cell. Fuel cells can operate virtually continuously as long as the necessary flows are maintained.

I put my foot in mouth all of the time. Once you get used to the taste of gritty rubber, it's not so bad :-)
