is a nickel electrode similar to the anode used in nickel-cadmium storage batteries, etc., and is, for example, a sintered nickel electrode. The cathode 7 is an electrode plate made by coating carbon powder with Pt and Pd added as catalysts and using polytetrafluoroethylene as a binder and molded onto a metal substrate, or one using nickel powder instead of carbon powder. , or a nickel sintered body impregnated with Pt or Pd. The cathode 7 has one outer side surface coated with polytetrafluoroethylene to make it water repellent. The separator 8 is made of asbestos, polypropylene, or the like. Further, the electrolytic solution introduced into the single cell case 2 is a KOH aqueous solution, and the amount thereof is such that it can be held by the electrode plates and the separator.

でもよい。 Furthermore, a liquid port plug 9 is attached to the upper part of the single cell case 2. The liquid port plug 9 is installed in an electrolyte injection opening provided in the single cell case 2, and has a vent hole 10 through which liquid does not pass, but hydrogen passes through. Note that liquid does not pass through the vent hole, but hydrogen does pass.A porous synthetic resin membrane, such as a polypropylene or polytetrafluoroethylene thin film, is installed to cover the opening, and as a result, liquid does not pass through, but hydrogen does. It may also be provided with a large number of ventilation holes. Of course, a single cell case may be provided with a liquid port plug in which a relatively large through hole previously provided is covered with a porous synthetic resin film.
