Good questions:

1) Special Equipped Hydrogen Fuel dispensers are set up in both the Washington DC area and in and around Los Angelos CA. One of the qualifications for getting one of these cars is that the individual had to live within 20 miles or less of one of these facilities. One of the reasons that GM, Honda and BMW have embarked on these pilot programs is to help convince the government to invest in the necessary infrastructure to support hydogen cars

2) In it's gaseous state Hydrogen is very volitile. In the fuel cell cars however Hydrogen is kept in its liquid state at very low temperatures. Both GM and Honda have built in a number of redundant systems to keep their respective cars safe in the event of a collision( reinforced tanks, additional structure and cooling systems) The cars are no more likely to catch fire than a standard ICE vehicle.
