They're not producing fuel to continue the same reactions, which would be a violation of conservation of energy. They're producing fuel to run a different reaction. Less "perpetual motion machine," more "spinning a turbine to charge a battery to run an EV."
Edit: A better analogy is cracking water to capture the hydrogen, to later burn it in a fuel cell.
