要約
(EN)
 A direct oxidation-type fuel cell system is provided with: a fuel cell that generates electric power from fuel and an oxidizing agent gas; a positive-displacement pump for supply oxidizing agent gas to the fuel cell; a pump power supply that applies a drive voltage to the pump; an oxidizing agent gas flow-directing part that suppresses pulsations in the discharge pressure of the pump; a pressure sensor that detects the discharge pressure of the pump; a load current sensor that detects the load current of the fuel cell; a voltage sensor that detects the drive voltage of the pump; a first memory that stores first information pertaining to the target supply flowrate of oxidizing agent gas to the fuel cell predetermined according to correspond to the load current; a second A memory that stores second A information concerning the relationship between the drive voltage of the pump, the discharge pressure of the pump, and the target supply flowrate; and a controller that controls the supply flowrate of oxidizing agent gas supplied to the fuel cell, on the basis of the first information, the second A information, the value detected by the pressure sensor, the value detected by the load current sensor, and the value detected by the voltage sensor.
