PROBLEM TO BE SOLVED: To provide a fuel cell control system which can obtain the maximum power generation efficiency of a membrane electrode assembly without causing the membrane electrode assembly to degrade.SOLUTION: A fuel cell control system 20 comprises: a fuel cell 10 including an electrolyte membrane and electrodes disposed on both sides of the electrolyte membrane; a fuel gas supply unit 300 which supplies fuel gas to the fuel cell; an oxidation gas supply unit 400 which supplies oxidation gas to the fuel cell; a coolant supply unit 500 which supplies a coolant to the fuel cell; back pressure adjustment units 340, 440 which adjust the back pressure of at least one side of the fuel gas and the oxidation gas; a thermometer 530 which detects a temperature equivalent to the cell temperature of the fuel cell; and a control unit 700 which controls the operation of the fuel cell. During the aging operation of the fuel cell, the control unit 700 controls at least one of the cell temperature, a flow rate of the fuel gas or the oxidation gas, the back pressure, and a current density of the fuel cell, to maintain the water in the fuel cell existing as a liquid phase. |
