1. A power supply apparatus for offering a voltage to be used with a load, said power supply apparatus comprising:

  • a fuel cell assembly performing an electrochemical reaction to generate an input voltage;

    a feeding device having therein a fluid fuel and in fluid connection with said fuel cell assembly so as to introduce said fluid fuel into said fuel cell assembly;

    a blower for introducing ambient air into said fuel cell assembly;

    a detecting circuit electrically connected to said load, detecting an operating voltage of said load, and generating a triggering signal in response to the detecting result; and

    a converting circuit electrically connected between said fuel cell assembly and said detecting circuit, converting said input voltage into said operating voltage in response to said triggering signal, and offering said operating voltage to said load.
