OSTI ID:6304299
A hydrogen fuel system is described for use in conjunction with and as an alternative to a hydrocarbon fuel system in a motor vehicle or other apparatus having a combustion unit and a mixing device for mixing hydrogen gas with air for introduction into the combustion unit. The hydrogen fuel system includes a hydrogen storage tank for holding hydrogen under pressure, a conduit for conveying hydrogen gas from the tank to the mixing unit, and a solenoid disposed in the conduit and responsive to a first signal for allowing the flow of hydrogen gas to the mixing unit, and responsive to a second signal for preventing flow of hydrogen gas to the mixing unit. Also included is a hydrocarbon fuel tank, a conduit for conveying fuel from the fuel tank to the combustion unit, and a fuel pump responsive to the first signal for preventing flow of fuel from the fuel tank to the combustion unit , and responsive to the second signal for pumping fuel to the combustion unit. A two-position, manually operable switch is provided to produce the first signal when in a first setting and the second signal when in a second setting.
