Right, so you can use electricity to make h2 at less than 100% efficiency then lay pipes all around the city to move the h2 to the stations, or build giant trucks that can transport the h2 on the roads (and pay drivers). On the other hand you can transport the electricity directly into the car using copper wires that are already in place

No, I mean connect your fuel cell car to a hose, and an electrical outlet at the end of the day, and run the fuel cell in reverse to regenerate the H2.

I saw it in a science fair, they could switch directions of the fuel cell to go either way.
