Zusammenfassung:A fuel cell system includes a plurality of fuel cell stacks (1A to 1C) and a plurality of power controllers (2A to 2C) corresponding to the plurality of fuel cell stacks (1A to 1C) on a one-to-one basis. In the fuel cell system, a number of fuel cell stacks (1) under operation is varied according to a load, only one of the plurality of power controllers (2A to 2C) is set as a master power controller, and power controllers other than the master power controller are set as slave power controllers. The master power controller is set such that operation times of fuel cell stacks connected to the slave power controllers become longer than an operation time of a fuel cell stack connected to the master power controller.
