PURPOSE:To decrease electrolytic voltage and to improve current efficiency, by using the structure of a joined body obtained by allowing a thin film layer of an ion exchange resin to exist on one surface of a porous electrde and a thin layer of a material having catalytic activity for electrolytic reaction to exist thereon. CONSTITUTION:This structure of a joined body is the 3-layered structure of a porous electrode-thin film-an ion exchange resin-thin layer-an electrode catalyst. More specifically, the thin layer of the ion exchange resin of <=40mu thickness is deposited on one surface of the porous electrode of 30-90% porosity and 0.1-100mu average grain size having a specific shape. The thin layer of the material having catalytic activity for electrolytic reaction is stuck on the thin film layer. The thin layer of the cathodic activity material is stuck on the thin film layer of the resin when the thin film layer of the resin is formed on the porous electrode that can serve as an anode as a substrate in the electrolysis of an alkali metal halide in this case. Conversely, the thin layer of the anodic activity material is stuck thereon in the case of the porous electrode that can serve as a cathode. |
