BB, yes in this case. But if there was no fuel cell system and as AnneOwl said 'why not just use a battery'. Solar would take an age to recharge it unless you had a huge array, and there would need to be a means to rapid charge the battery.
So yes, the battery is not to be rapid charged in this system, just trickle charged from excess energy generated by the cell.
