Abstract
A fuel cell system that includes a fuel cell and a secondary battery, each acting as a power supply source. A first converter a second converter is provided between the fuel cell and the secondary battery and first and second loads. A first inverter is provided between the first and second converters and the first load and a second inverter is provided between the first and second converters and the second load. A first controller controls an output of the fuel cell by controlling the first converter, and a second controller is configured separately from the first controller. If one of the first controller and the second controller receives the failure information sent from the other, the first controller or the second controller that has received the failure information stops operation of the control target thereof.
