Exactly. Until someone comes up with some magic to crack the Hydrogen from Oxygen as needed, its little more than a novelty for cars.
Hell I wish they would come up with decent fuel cell tech for home use.
Don’t forget the fuel cell buses that a lot of transit agencies put out there for show. They would be shocked to learn that their “zero-emissions” bus that emits “only water from the tailpipe” is emitting the one true and actual “greenhouse gas”.
