START CONTROL DEVICE FOR FUEL CELL SYSTEM

摘要

At a time of starting a fuel cell when solenoids of control valves such as a check valve and a discharge valve are in a frozen state, hot air obtained by adiabatic compression at an air supply portion is divisionally supplied into a warm-up box through a warm-up valve. It is determined whether the discharge valve is opened by determining whether the discharge fuel gas pressure Pout is reduced below a predetermined pressu re while the check valve is in an opened state. After confirming that the discharge valve has been opened, it is determined whether the check valve can be closed by determinin g whether the pressure near the fuel supply port of the fuel cell has risen above the predetermined pressure stored in the memory. The warm-up operation of the fuel cell can thereby be efficiently conducted and the fuel cell can be reliably started.
