Well, in terms of energy density, you are alright: https://en.wikipedia.org/wiki/Energy_density https://en.wikipedia.org/wiki/Energy_density ... but not in terms of power/weight for the motor (or fuel cell in this case): https://en.wikipedia.org/wiki/Power-to-weight_ratio#Fuel_cell_stacks_and_flow_cell_batteries https://en.wikipedia.org/wiki/Power-to-weight_ratio#Fuel_cel... ... You'd need about 1000lbs of weight for 200hp equivalent. Also, I'd rather be surrounded by hydrogen than jet fuel :).
