The hydrogen gas injector is the main component in the hydrogen supply path of a fuel cell-electric vehicle. When so requested by the fuel-cell control unit, the component feeds the necessary quantity of hydrogen for the stack in a fuel-cell system. In addition, the valve features a shut-off function for separating the medium-pressure stage from the fuel-cell stack.
