There's nothing stopping FCEVs from being as efficient as BEVs. Even now, huge improvements are being found like 90% efficient electrolysis[1]. Future improvements in hydrogen and fuel cell technology could close the gap entirely.
Like I said, you're repeating many arguments that are a mirror of the arguments made against BEVs. It's pretty ridiculous to just repeat anti-EVs for something else while being pro-EVs.
The other thing is that this viewpoint is increasingly outdated. A lot of these "facts" date to the 2010s or earlier. These are more inline with a person being out of touch than someone that is informed.

- DuskStar 6y ago90% efficient electrolysis doesn't matter when "getting hydrogen from the pump to your car's fuel tank" has 20+ percent energy losses. And from the tanker trailer to the pump. And... This comes from the inherent thermodynamic inefficiencies of compressing something, letting it expand, and then compressing it again.
- Hypx 6y agoThose losses can be made much less than that. Theoretical minimal losses are on the order of 1-2kWh per kg, and in practice not much more than that[1]. Further efficiency improvements can get reality even closer to theoretical. Most of these arguments are increasingly outdated, as I mentioned before. We're at the point where hundreds of billions of dollars are being spent on hydrogen right now[2]. So naysayers are more accurately described as being out of touch with latest events and not people with any special knowledge.
