PURPOSE:To perform supplementary feed of electrolyte without downtime and complication of battery construction by connecting in parallel and disconnectably an electrolyte spraying device in an inlet pipe line of fuel gas. CONSTITUTION:An electrolyte supplementary feed system 40 includes as main constituent an electrolyte spraying device 41. The spraying device 41 is connected in parallel to a fuel gas inlet valve 32 of a fuel gas inlet pipe 31 in a fuel gas system 30 through switching valves 42, 43 disposed in front and at the back of the spraying device. The concentration of electrolyte to be sprayed by the spraying device 41 depends upon the kind of the spraying device, and in general, opening degress of the fuel gas inlet valve 32 and switching valves 42, 43 are properly adjusted so that a part or corresponding part of the fuel gas flows into the spraying device 41 to adjust the concentration of the electrolyte in the fuel gas flowing into a battery in such a manner as to be held in the range. This allows the electrolyte mixed in the fuel gas P to be penetrated into a matrix layer 1. Thus, supplementary feed of electrolyte can be performed without downtime and complication of battery construction. |
