Abstract

PURPOSE:To easily suppress the differential pressure between electrodes by taking in or out a filler by operation from the outside in or from at least one space of a manifold and a cell container. CONSTITUTION:A pipeline and an equalizing valve 28 used to equalize the pressure of cathode has and that of nitrogen gas in a container in emergency stop are installed, and welded to a jacket wall used to store a filler 3 inside a cell container 1. As the filler 3, a liquid having high boiling point, good heat resistance, and good heat insulation is used. When the supply of a reaction gas is stopped by emergency stop, the pressure in a fuel cell is gradually decreased and the fuel cell stops its operation at last. At that time, the equalizing valve 28 is operated, and the pressure in the cell container and that of cathode gas are equalized. Since the volume in the cell container is freely adjusted, the pressure drop in the cell container is easily adjusted. Since the pressure in the cathode is adjusted to almost equal to the pressure on an anode side, the differential pressure between both electrodes and that between a reaction gas and the cell container are easily suppressed.
