Abstract
PURPOSE:To prevent the electrolyte from absorbing a moisture to be diluted, by operating a supply of reaction gas from a sub-feed tube, having a dehydrater, when stopping the operation, with the reaction gas supply system made into two systems of reaction gas main feed tube and reaction gas sub-feed tube. CONSTITUTION:To an oxidant compartment room 5 of a fuel cell 1, comprising a hydrogen electrode 2, air electrode 3, porous matrix 19 with phosphoric acid impregnated, etc., are connected a main feed tube 10, for supplying air, sub-feed tube 12, provided in parallel to the main feed tube 10, and an air drawn-out tube 13, for drawing out an air. The sub-feed tube 12 provides a dehydrater 11 with the connection made to the main feed tube 10 by thee-way valves 14, 15. When stopping the operation, with a load 18 turned off and drawnout valves 9, 17 closed, the three-way valves 14, 15 are switched from the main feed tube side 10 to the sub-feed tube 12 side, causing a supply of hydrogen as natural diffusion from a hydrogen supply tube 6 and a supply of air dehydrated as natural diffusion through the sub-feed tube 12 having the dehydrater 11.
