My understanding (I'm sure someone will correct me if I'm wrong) is that the production of H2 for fuel cell-based cars isn't the problem, but
rather the storage of H2 at high densities.
Apparently, the current technology limits the pressure that hydrogen can safely be stored at. This, in turn, limits the effective range of the car.
Hydrogen, after all, is the most abundant element in the universe.
