Seems to me that a massive battery is cheaper than a massive fuel cell, 
certainly cheaper to operate.

In short, architecture of parking structures, home garages, tunnels, and other 
closed storage for vehicles needs to be vented, though the steps needed are not 
far beyond those for gasoline-powered cars.

Why? If you design it to run for 8 hours then at the end of the work day charge 
overnight. I believe that is Tesla’s idea by making a truck with a range of 300 
to 500 miles.

It still doesn't make any sense. The solar they are using to make hydrogen 
could be more efficiently used to just charge batteries.
