  • Patent number: 11302941
    Abstract: A pressure-based latching switch includes a shuttle valve, a first valve and a second valve. The shuttle valve may switch a fuel through one of a first port and a second port in response to a greater pressure of the fuel at the ports. The first valve may switch a fuel to the first port while a second pressure of the fuel at the second port is less than a second threshold pressure. The second valve may switch the fuel to the second port while a first pressure of the fuel at the first port is less than a first threshold pressure. The pressure-based latching switch may change the fuel supplied to the fuel cell system automatically from a first fuel tank to a second fuel tank in response to the first pressure of the fuel falling below the first threshold pressure.
