Even with a 93% efficiency adding the energy needed to compress the hydrogen and the fuel cell efficiency you arrive at an efficiency of 48%, pretty much half as the batteries.
- darksaints 7y agoI can dispute those numbers too but that is beside the point. Batteries are probably good enough in energy density for most car users, and they do have an efficiency advantage (not as great as you're trying to portray but still better). For 99% of car buyers, that's a better option. But fuel cells still have a place where energy density is a major concern. That's likely to be the case for commercial vehicles, where long recharge times and low ranges are unacceptable.
