As the electrolyte (polymer ion exchange membrane) 2, a fluororesin polymer ion exchange membrane (for example, a fluororesin ion exchange membrane having a sulfonic acid group) is used, and the catalyst electrode is made of, for example, platinum on both sides with this center. (Negative electrode) 3 and catalyst electrode (anode) 4 are attached, and both surfaces thereof are sandwiched and sandwiched by porous carbon electrode (negative electrode) 5 and carbon electrode (anode) 6.

がある。The hydrogen introduced into the fuel cell main body through the flow channel of the separator 7 usually has a hydrogen ion permeability of the polymer ion exchange membrane, which is the electrolyte 2, so that the hydrogen is normally introduced before introduction into the fuel cell. The steam corresponding to the saturated steam partial pressure in the vicinity is contained, that is, humidified before being introduced. Oxygen or air may be humidified for the same reason.

At this time, since hydrogen ions move from the negative electrode to the anode along with x H 2 O, the water vapor introduced together with hydrogen gradually permeates to the anode side along the hydrogen flow path direction and approaches the dry gas.

I will end up. Therefore, when trying to increase the area of the electrolyte or the area of the electrode assembly, the water vapor that has humidified the hydrogen is H + ・ In the form of xH 2 O, it gradually permeates to the oxygen or air side, the water vapor pressure becomes low near the end of the hydrogen flow channel groove, and it approaches a dry gas, and the water retention state of the polymer ion exchange membrane that is the electrolyte can be maintained.
