摘要： A controller for a fuel cell system controls generated power of a fuel cell stack by switching a generation state of the fuel cell stack based on a state of charge of a power storage device. The generation state includes a first generation state, in which the fuel cell stack is caused to generate a first generated power, a second generation state, in which the fuel cell stack is caused to generate a second generated power greater than the first generated power, and a third generation state, in which the fuel cell stack is caused to generate a third generated power greater than the second generated power. The controller calculates a power reference value indicating an actual result of power generation of the fuel cell stack from the detected generated power of the fuel cell stack, and updates the second generated power based on the power reference value.

摘要： A solid oxide fuel cell is provided with which the further advance of degradation can be restrained relative to fuel cell units in which degradation has advanced. The present invention is a solid oxide fuel cell system which varies output power in response to a required generation amount. The system comprises a fuel cell module furnished with multiple fuel cell units, a fuel supply device for supplying fuel to the fuel cell module, an oxidant gas supply device for supplying oxidant gas to the fuel cell module, and a controller for changing the amount of fuel supplied from the fuel supply means in response to the required generation amount. The controller reduces the rate of change in the fuel supply amount per unit time when the required generation amount changes subsequent to an estimate or determination that the fuel cell module has degraded.
