Abstract
A power supply apparatus includes a fuel cell assembly, a feeding device, a blower, a detecting circuit and a converting circuit. The fuel cell assembly performs an electrochemical reaction to generate an input voltage. The feeding device has therein a fluid fuel and in fluid connection with the fuel cell assembly so as to introduce the fluid fuel into the fuel cell assembly. The blower is used for introducing ambient air into the fuel cell assembly. The detecting circuit is electrically connected to the load, detects an operating voltage of the load, and generates a triggering signal in response to the detecting result. The converting circuit is electrically connected between the fuel cell assembly and the detecting circuit, converts the input voltage into the operating voltage in response to the triggering signal, and offers the operating voltage to the load.
