For the same reason that battery cells will improve, the fuel cell technology that convert the hydrogen will improve as well.
Also, another thing to consider, where do all the old batteries go? The same thing has to be considered for hydrogen fuel cells, but there could potentially be many more old batteries to deal with from battery powered cars, than from hydrogen powered cars.
