heres a site that addresses most of the misconceptions out there about hydrogen
http://www.generalhydrogen.com/tech_hydrogenmyths.shtml

 

maybe the car only supports 1 gallon of gasoline?

 

yeah thats what im thinking

it has a 1 gallon gas tank with 1 gallon of highly compressed hydrogen in it

normally hydrogen fuel is measured by kilograms or lbs and that mileage ratings are converted from the equivalent of that in litres or gallons in natural state.

so ford cheated in getting this 350mpg ratings
