PURPOSE: An electric valve controller of fuel cell system is provided to reduce danger of leakage or explosion due to continuous inflow of fuel at power outage, and to minimize the power consumption after absolutely opening an electric valve. CONSTITUTION: An electric valve controller(100) of fuel cell system controls an electric valve(10) by being connected to the first terminal, the second terminal and the third terminal of the electric valve, and comprises an opening/closing circuit(110) and a power saving circuit(120). When receiving power from outside, the opening/closing circuit opens the electric valve. When stopping the supply of external power, the electric valve is closed. |
