FUEL BATTERY SYSTEM

Abstract:

A fuel battery system in which the complexity of a constitution is able to be minimized is provided. A fuel battery system includes a battery (11), a motor (13), a fuel battery stack (15), and an electric power control unit (17). The electric power control unit (17) includes a battery control unit (21) connected to the battery (11), first and second bridge circuits (23A and 23B) connected in parallel with and integrated with the battery control unit (21), and an electric power control unit (25) including the second bridge circuit (23B) and a three-phase reactor (35). The electric power control unit (25) is connected to the fuel battery stack (15) so that stepping-up control is possible.
