    • The object of the present invention is to provide a thin and light electrochemical device using a solid polymer electrolytic film, which is capable of maintaining its steady performance for a long time even at a high humidity condition and a process for preparing the same. The device comprises inserting and pressuring the jointed electrochemical device 10 between a pair of pressing plates 30 and 31, wherein the jointed electrochemical device 10 is obtained by jointing the anode and the cathode having a catalytic layer on a base substrate of conductive porous material to both sides of the solid polymer electrolytic film, and wherein the pressing plates have the opening part having an area smaller than an electrochemical reaction part formed by facing the anode and the cathode.
    • 本发明的目的是提供一种使用固体聚合物电解质膜的薄且轻的电化学装置,即使在高湿度条件下也能够长时间保持其稳定性能及其制备方法。 该装置包括在一对压板30和31之间插入和加压接合的电化学装置10,其中通过将具有催化层的阳极和阴极在导电多孔材料的基底上连接到两者上而获得接合的电化学装置10 固定聚合物电解质膜的侧面,并且其中,所述压板的开口部的面积比由阳极和阴极形成的电化学反应部的面积小。
