PROBLEM TO BE SOLVED: To produce an electrolyzing functional element having a difficult-to- release structure by laminating a base material, a catalyst bed and a moisture- permeable and water-repellent thin film successively on both side faces of a solid high molecular electrolyte membrane under specified conditions to form an anode and a cathode. SOLUTION: The base materials 11 and 21 having many through-holes 31 and 32 tapering toward the inside from the outside and consisting of a perforated metallic sheet to be used as a current collecting sheet are provided on both side faces of a solid high molecular electrolyte membrane 3 (made of naphion), and a part of the membrane 3 is bulged out from the through-holes 31 and 32 and convexed. The catalyst beds 12 and 22 contg. a platinum catalyst grain and a solid high molecular electrolyte are formed on the surfaces of the base materials 11 and 21, the beds 12 and 22 are covered with moisture-permeable and water-repellent thin films 13 and 23 to form an anode 1 and a cathode 2, and an electrolyzing functional element is produced. As a result, an electrolyzing functional element capable of dehumidifying a material 5 and difficult to release is produced at a low cost. |
