A direct oxidation fuel cell system including: a fuel cell which generates power from fuel and oxidant gas; a positive displacement pump for supplying the oxidant gas; a power supply for applying drive voltage to the pump; an oxidant gas flow conditioning unit for inhibiting pulsation of discharge pressure of the pump; a pressure sensor for detecting the discharge pressure; a load current sensor for detecting load current of the cell; a voltage sensor for detecting the drive voltage; a first memory for storing first information on a target supply flow rate of the oxidant gas, set based on the load current; a second memory for storing second information on relation of the drive voltage, discharge pressure, and target supply flow rate; and a controller for controlling flow rate of the oxidant gas, by using the informations, and values from the pressure, load current, and voltage sensors. |
