Abstract:
1. A fuel cell power generation system comprising: a fuel cell that serves as a first power source for generating power upon receipt of fuel supply; a direct-current adjusting unit capable of adjusting a direct current generated by the fuel cell into a direct current controlled at one of a target voltage, a target current, and a target power; a first power supply unit that supplies power to a power line extending between a second power source and a load using the adjusted direct current; a second power supply unit that supplies a predetermined direct current power to an accessory that is driven by the predetermined direct current power using the adjusted direct current output; a power failure detecting unit that detects power failure of the second power source; and a controller that controls: the direct-current adjusting unit such that the direct current generated by the fuel cell is adjusted to a value corresponding to a direct current at the target voltage established for the power failure when the power failure of the second power source is detected by the power failure detecting unit; wherein the first power supply unit interrupts the power supply to the power line and the fuel cell performs the power generation based on a power needed to operate the accessory during the power failure of the second power source.
