４倍の面積に拡大することができた。Further, together with the hydrogen ions H + , water having an average of about 3 molecules moves from the anode 20 to the cathode 21. Therefore, in the cathode 21, excess water moves from the anode 20 to the cathode 21 together with the water generated by the reaction of the formula (5), and the humidity of the dehumidifying space on the anode 20 side is lowered. Also,
The solid polymer electrolyte membrane 15 has holes 16 in the porous members 16 and 17.
Since they are projected from a and 17a, the reaction area with the catalyst layers 18 and 19 is increased, and the dehumidification performance is improved. Further, since the catalyst layers 18 and 19 are formed by mixing the solid polymer electrolyte component and platinum powder, the platinum powder is distributed in layers. Therefore, the total thickness of the catalyst layers 18 and 19 is 3
Since the reaction surface exists dimensionally, the reaction area increases,
Dehumidification performance is improved. With the above configuration, the conventional dehumidifier has a dehumidifying performance of 0.1 g / h / 10.
With respect to 0 cm 2 , in the present invention, 0.7 g / h / 100c
m 2 was obtained. Further, since the power supply members 22 and 23 are arranged in a grid pattern so that the currents evenly flow between the respective poles 20 and 21, even if the effective reaction area is 400 cm 2 / unit, the performance per unit area decreases. It was possible to expand the area to 4 times the conventional size.
