Abstract
Abstract A polymer-gel-coated conductor has a conductor member and a cross-linked polymer in a gel state. The polymer in gel state contains an electrolyte and coats the conductor member. An oxidative product or a reduction product of an organic matter or an inorganic matter has been precipitated on the surface of the conductor member or in the region of the polymer in gel state near the surface of the conductor member. Also disclosed are a method of producing the polymer-gel coated conductor and an electric cell in which at least one of a pair of electrodes is made of the polymer-gel-coated conductor.
