FUEL CELL, FUEL CELL CONTROL METHOD, AND COMPUTER PROGRAM

WIPO Patent Application WO/2017/163553

A1

Provided are a fuel cell, a fuel cell control method, and a computer program such that freezing is prevented by suppressing residual water inside an air-liquid separator when power generation is stopped, water drainage can be satisfactorily carried out at a subsequent power generation time, and a decrease in the fuel cell function can be prevented. This fuel cell (300) comprises: a stack (1); a hydrogen supply unit (200); opening-closing valves (21, 79, 80) for supplying hydrogen; hydrogen circulation paths (72, 73, 75) wherethrough a gas evacuated from the stack (1) circulates to be returned to the stack (1); a first pressure sensor (78) detecting the pressure inside the hydrogen circulation path; an air-liquid separator (83) separating water from the gas; water drainage valves (84, 85) for discharging water from the air-liquid separator (83); and a control unit (9) controlling the opening/closing of the opening-closing valves and the water drainage valves. On the basis of the internal volume of the hydrogen circulation path, the internal volume of the air-liquid separator (83), and the pressure detected by the first pressure sensor (78), the control unit (9) controls the opening/closing of the opening-closing valves and the water drainage valves to carry out water drainage control processing.
