Abstract: A fuel cell system power supply includes: a fuel cell stack configured to react hydrogen and oxygen in air with each other in order to generate electricity; a high-voltage converter configured to boost output power of the fuel cell stack; and a high-voltage junction unit configured to transmit the output power of the fuel cell stack to the high-voltage converter and to receive high-voltage power from the high-voltage converter. The high-voltage junction unit has a structure configured to simultaneously accommodate an output terminal of the fuel cell stack and an input terminal of the high-voltage converter. Consequently, the assembly structure of the high-voltage junction unit may be simplified, whereby productivity may be improved. In addition, maintainability may be improved, whereby it is possible to efficiently maintain a fuel cell vehicle.
