A:
That depends on how they're charged. A hydrogen fuel cell plays the same general role as a battery. If they're charged up using solar power, for example, then they use mostly renewable resources. If they're charged up with power obtained from fossil fuels, then they use non-renewable resources. Unfortunately almost all plans for hydrogen fuel cells are based on the same non-renewable energy sources which are now in use, just as almost all batteries are now charged from non-renewable power sources.
