And it's impractical to swap a battery that weighs hundreds of pounds. Maybe one day, we'll have cranes that lift it out and drop a replacement in and a system for doing it quickly.
The biggest problem with the h2 cell is the availability of hydrogen. It takes a lot of energy to remove it from water or methane.
