PURPOSE:To recover an electrolyte exhausted from each cell and to return it to the original cell with almost no pressure loss by installing a barrier having a porous member catching an electrolyte exhausted in forms of vapor and mist together with a reaction gas. CONSTITUTION:A receiver 1 which is protruded from the side of a stack within an a manifold and receives an excess electrolyte dropping along the side is installed. A barrier 10 having a porous member which restricts a reaction gas passage 12 between adjacent receivers with a part of it openend and catches an electrolyte exhausted in forms of vapoe and mist together with a reaction gas from a projection-recess-shaped reaction gas passage is installed. The barrier 10 and the receiver 1 recover the electrolyte vapor and electrolyte mist from each cell and return the recovered electrolyte to the original cell. Since the barrier 10 does not close the reaction gas passage, almost no pressure loss is produced. The electrolyte exhausted from the cell is surely recovered and returned to the original cell. |
