Hydrogen fuel cell cars could one day challenge electric cars in the race for pollution-free roads—but only if more stations are built to fuel them.
Honda, Toyota and Hyundai have leased a few hundred fuel cell vehicles over the past three years, and expect to lease well over 1,000 this year. But for now, those leases are limited to California, which is home to most of the 34 public hydrogen fueling stations in the U.S.
Undaunted, automakers are investing heavily in the technology. General Motors recently supplied the U.S. Army with a fuel cell pickup, and GM and Honda are collaborating on a fuel cell system due out by 2020. Hyundai will introduce a longer-range fuel cell SUV next year.
"We've clearly left the science project stage and the technology is viable," said Charles Freese, who heads GM's fuel cell business.
Like pure electric cars, fuel cell cars run quietly and emission-free. But they have some big advantages. Fuel cell cars can be refueled as quickly as gasoline-powered cars. By contrast, it takes nine hours to fully recharge an all-electric Chevrolet Bolt using a 240-volt home charger. Fuel cells cars can also travel further between fill-ups.
Would you rather trade in your gas-guzzler for a hydrogen fuel cell car, or an electric car?

> Pressurized hydrogen has been chosen by the industry but it's not the only possible method.
The U.S. government evaluated several methods. On page 6 of their report, they show cryogenic storage of hydrogen, or adsorption on the metal-organic framework MOF-177 as having greater capacity than pressurised storage at 700 atm. MOF-177 adsorbs the most hydrogen when it's cold and when significant pressure is applied. From pages 33 and 34 of their report I see that they studied it at 100 K and 250 atm.

I found the link to the report in Wikipedia's article about hydrogen storage:
