PURPOSE:To effectively cool without losing the balance of electrolyte concentration and generation of leakage current by connecting a cooling tube arranged in an electrolyte chamber to a coolant circulation line. CONSTITUTION:When an electrolyte chamber 4 is filled with electrolyte and reaction gases are supplied to a fuel electrode 2 and an oxidizing agent electrode 3 to operate a fuel cell, heat is generated by polarization of each electrode and liquid resistance of the electrolyte, and the temperature of electrolyte is increased. When a pump 9 in a coolant circulation line 11 is operated to circulate coolant between a cooling tube 7 and the circulation line 11, heat generated in the fuel cell 1 is transferred by the coolant flowing within the tube 7 from the cell and exhausted outside with a heat exchanger 8, and the coolant cooled in the heat exchanger 8 is circulated again to the cell 1. Since a power generating line and a cooling line are separated, the fuel cell is effectively cooled without an adverse are separated, the fuel cell is effectively cooled without an adverse effect on power generation such as break of balance of electrolyte concentration. |
