Abstract
An object of the present invention is to provide a fuel cell system suited for changing a drive operating point of a fuel cell at the time of low-efficiency power generation. The fuel cell system in accordance with the present invention includes a fuel cell which generates electric power by supplied reactant gases, an air compressor which adjusts the flow rate of a reactant gas supplied to the fuel cell, and a controller which controls an output current of the fuel cell by controlling the air compressor to change a drive operating point of the fuel cell. The controller sets a restriction on at least one of a current change amount and a voltage change amount per unit time when changing the drive operating point of the fuel cell in a range of low-efficiency power generation in which a power loss is larger than that in normal power generation.
