電流密度を高くし、かつ安定した電圧で電解するために
は水蒸気供給膜の透水量を多くする必要がある。When the electrolysis current density is set high in the conventional steam electrolysis cell of FIG. 5, the amount of water vapor supplied is small because the amount of water permeation of the steam supply film G used in the water electrolysis cell is small. There is a problem in that the solid polymer electrolyte E may be in a dry state and the electrolysis voltage may sharply increase. Therefore, in order to increase the electrolysis current density and perform electrolysis at a stable voltage, it is necessary to increase the water permeation amount of the water vapor supply membrane.

以下、本考案の一実施例の静的水蒸気供給方式水電解装
置を第１図によって説明する。Hereinafter, a static steam supply type water electrolysis apparatus according to an embodiment of the present invention will be described with reference to FIG.

(DuPont product name), the water vapor supply membrane is placed in a sealed glass container filled with water and heated to about 140 ° C. (the container pressure at this time is about 2.5 kg / m 2 in gauge pressure). G) It was kept for about 1 hour, allowed to cool after 1 hour, and when the water temperature returned to room temperature, the water vapor supply membrane was taken out of the container. The water content of the water vapor supply film C in this state and the water content of the untreated one were 50 to 60% and 24 to 35%, respectively.

透水量は0.022ml/minであった。The autoclave-treated steam supply film C was incorporated into the apparatus shown in FIG. 1, and the relationship between the water permeation amount of the steam supply film C and the pressure in the water supply chamber F was determined. Similarly, the steam supply membrane G that was not autoclaved was incorporated into a steam electrolysis cell, and the relationship between the water permeation amount and the pressure in the water supply chamber was determined. As a result, as shown in FIG. 2, when the pressure in the water supply chamber of the water electrolysis cell was set to be the same as 2 kg / m 2 G, the permeation rate of the autoclaved membrane C was 0.058 ml / min. The water permeation rate of the conventional membrane G that had not been autoclaved was 0.022 ml / min.

Three times as much current can be passed.

過ぎなかった。Further, the maximum current density when electrolysis was carried out using the steam supply film C autoclaved in this example was about 50 A / dm 2 as shown in FIG. On the other hand, when electrolysis was performed using the conventional steam supply film G without autoclaving, the maximum current density was only about 20 A / dm 2 .

置のコンパクト化が可能となる。When the water supply chamber pressure is the same, the water permeation rate of the steam supply membrane subjected to the autoclave treatment is about three times higher than the water permeation rate of the water vapor supply membrane not subjected to the autoclave treatment. Also, the electrolysis current value and the water consumption amount are calculated according to Faraday's law,
Due to the proportional relationship (Fig. 3), the electrolysis current density when using the autoclaved membrane is set to be about 3 times higher than the electrolysis current density when using the non-autoclaved membrane. be able to. By setting the electrolysis current density three times higher, the amount of oxygen and hydrogen generated also triples, and when obtaining the same oxygen and hydrogen as in the conventional method, the area of the solid polymer electrolyte can be reduced to about 1/3, It can be made compact.
