摘要
A power supply system and a fuel cell backup power system thereof are provided. The power supply system includes: a mains power supply module for providing mains electricity to a load, and a fuel cell backup power system for providing electricity to the load while the mains electricity provided by the mains power supply module is insufficient. The fuel cell backup power system includes a fuel cell system, a power conditioning module, a battery, and a controller. The fuel cell system and the battery output first and second electrical energy, respectively. The controller defines a plurality of output power requirement levels for the fuel cell system, reads the power required by the load, and adjusts the output ratio between the first and the second electrical energy in a stepwise manner according to the output power requirement levels so as to meet the power required by the load.
