Batteries more expensive than a fuel cell + a fuel tank? Especially since the
fuel tank technology still isn't ready for prime time?

Hydrogen powered engines have been around for over 30 or 40 years but no
good source of fuel.

Until very recently, no one could make a H2 engine that didn't produce lots of
NOx pollution - more than any gasoline engine. 30-40 years of prototypes that
can't be sold isn't too impressive.

?? My understanding from what reading I have done is that burning
hydrogen produces only water vapor. Where would the NOx come from?
