Title
Hydrogen car and fuel cell in engine compartment
Caption
Liquid hydrogen in a 75L insulated tank under the back seat powers this General Motors Opel Zafira European zero emission test car called the HydroGen 1. The stack of 195 fuel cells and the 74-horsepower electric motor fit into the engine compartment and weigh just 159 pounds. Electricity is generated directly in the fuel cells by the chemical reaction of H2 with O2 from the air. The vehicle has a range of 250 miles and can go from 0 to 60 mph in 16 seconds.
