A hydrogen fuel system for an aircraft is configured to provide hydrogen fuel to the engines for propulsion. The fuel system also may provide hydrogen fuel to a fuel cell arrangement to generate electricity for use on the aircraft. The fuel cell arrangement may be selectively coupled to the feed lines for the engines. A ventilation system regulates the pressure within the one or more fuel tanks and the feed lines. The ventilation system can vent hydrogen vapor to atmosphere or can transfer hydrogen vapor between the fuel tanks and the fuel cell arrangement. A jet pump and accumulator may pull vapor from the feed lines as needed.
