if you look at the last paragraph, the dates for hydrogen vehice development, it says in 1991, they developed a hydrogen rotary? any pics of this vehicle?

Horridly low energy density & an extremely inefficient refining cycle are just side benefits, I guess.
Hydrogen works better for Japan because they don't have any resistance to using nuclear power for electrical generation - - which is the only way to make the hydrogen ICE fuel cycle efficient & clean enough to be a net pollution reducer.
When you use coal/natgas electrical generation for electrolysis, or natgas fractional cracking & catalysis for hydrogen production (as is done in the US), a hydrogen ICE ends up less efficient & overall more polluting than does a gasoline ICE.

People also don't have to drive as far in Japan, so the atrocious range is less of an issue.
Even if you use nuclear power, though, that's a huge waste of energy. If you're stuck on hydrogen, why not at least run it through a fuel cell to power an electric motor rather than just burning it? That makes no sense at all.
