3. Hydrogen isn't particularly efficent on the other end either though

Fuel cells are not that efficient, you multiply efficiencies so if you have 80% on either end your electric in to electric out is 0.8^2 = 0.64 so you are at 64% before you even start doing anything with the electricity, if your controller is 95% and your motor is 90% then it's .64*.95*.9 = ~.55 so your overall efficiency is only 55%.
