Oh yes there are!
Not many, admittedly.
But at the last count there were over 40 in California.
Heck, you've even got two in Illinois - one in Chicago (for the CTA
buses),
and a publicly-accessible one in Des Plaines.
Hydrogen may eventually be the fuel of choice, but it's still on the
horizon. I'm working on next-year stuff.

It won't be for cars anytime soon. A safe storage tank for H2 is a
bigger weight penalty than a battery.
H2 is a truly hell to handle. It ex-filtrates through most other
metals, makes Steel, (and other metals), brittle* as is does so, when
stored under pressure. It requires constant refrigeration in liquid form
with the same problems. It's a medium for transport of energy not a
source. NASA engineers who've worked with the stuff, will candidly
tell you that Kerosene/O2 rockets are much simpler to engineer with
fewer problems. I don't see how H2 as an Automobile fuel will ever be
wide spread without major advances in materials science.
