Product Guess – Using 1000+ Small Fuel Cell Units For Charging The Electric Car Battery?

I cant say I know much about fuel cells. So when I looked at a fuel cell I wondered. Since the membranes are stacked. Have the system a similar problem of efficiency as stacked peltier elements?

If so then it might be an idea to use many small thin fuel cell units. Look at Something like that.

What if you can make a small fuel cell unit very efficient and scale that thousands of times. Could this large cluster power something more than electronics?

I mean to charge the electric car battery on the go or at stops.
