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The other thing is that this viewpoint is increasingly outdated.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.
