Currently hydrogen fuel cells have a slight range advantage and speed of refueling advantage. However the efficiency of creating and compressing / liquifying hydrogen and then turning back into electricity in the cell is around half that of just charging a battery.

Fuels cells currently also don't put out as much burst power nor can they store energy from regenerative braking so a fuel cell car needs a traction buffer battery like a hybrid.

Pretty skeptical for hydrogen fuel cells at this point, battery cost are dropping fast while energy density going up along with charge rate, fuel cells are being left behind pretty quick.
