Not strictly true, (at the moment anyway), because it takes energy to create the hydrogen, then more energy to store it and then more energy is lost converting the hydrogen back to electricity in the fuel cell itself.
According to
Life cycle assessment of Polymer Electrolyte Membrane Fuel Cell applications* this makes battery vehicles over twice as efficient as fuel cell versions.
