1. one kind is used for the fuel cell temperature of fuel system and the method for stress management;

  • The fuel consumption device that said fuel system utilizes gas phase fuel to be fit to;

    Wherein fuel is roughly to be stored in the said fuel tank as liquid fuel and fuel fume near the vapor tension of fuel, and said method comprises step;

    Obtain the fuel feed pressure of said fuel system;

    Optionally extract the roughly fuel of liquid fuel of conduct from said fuel tank;

    AndOptionally extract the roughly fuel of fuel fume of conduct from said fuel tank;

    Wherein optionally extract the said step of fuel and be provided as the fuel of the variable ratio of liquid fuel and fuel fume for the said fuel system in said fuel tank downstream in response to said acquisition step, thereby at least one in following is provided;

    a) temperature of the fuel in the said fuel tank and pressure are regulated;

    And b) is the evaporated fuel of incomplete evaporation fuel to the vaporizer of said fuel system.
