experiment example 1
[0125] The cathode of the perfluorosulfonic acid electrolyte membrane was coated with Pt / C as a catalyst by means of spraying, decals, etc., and the iridium oxide catalyst with nanoporous structure was coated on the anode.
[0126] The anode is supplied with water through a water supply source, and the water is subjected to an oxygen evolution reaction to generate oxygen. In this case, the generated hydrogen ions move through the perfluorosulfonic acid electrolyte membrane, and an oxygen reduction reaction in which oxygen in the air is reduced and water is generated occurs in the cathode.
[0127] Figure 5 It is a graph showing the change of the oxygen generation current density with the voltage of Experimental Example 1.
[0128] Figure 5 Medium Pt / C-IrO 2 (Air-Water) means that Pt / C is used as the cathode catalyst, IrO2 is used as the anode catalyst, air is supplied to the cathode through a separate air supply unit, and water is supplied to the anode through a separate ...
experiment example 2
[0131] The cathode of the perfluorosulfonic acid electrolyte membrane is coated with platinum as a catalyst, and the anode is coated with a nanoporous structure of iridium oxide catalyst by means of spraying, decals, etc.
[0132] In this case, the unit cell was evaluated in the same manner as in Experimental Example 1, except that the water supply to the anode through the water supply source was cut off, and the air supply to the cathode through the air supply unit was cut off.
[0133] Image 6 It is a graph showing the change of the oxygen generation current density with the voltage of Experimental Example 2.
[0134] Image 6 Medium Pt / C-IrO 2 (Non Air-Non Water) means using Pt / C as cathode catalyst, IrO 2 Used as an anode catalyst, the supply of water to the anode through the water supply source is cut off, and the supply of air to the cathode through the air supply part is cut off.
[0135] refer to Image 6 , when 1.4V is applied, 0mA / cm is obtained 2 In this case...

[0137] The cathode of the perfluorosulfonic acid electrolyte membrane is coated with platinum as a catalyst, and the anode is coated with a nanoporous structure of iridium oxide catalyst by means of spraying, decals, etc.
[0138] In this case, the unit cell was evaluated in the same manner as in Experimental Example 1, except that water was supplied to the anode through the water supply source, but the air supply to the cathode through the air supply unit was cut off.
[0139] Figure 7 It is a graph showing the change of the oxygen generation current density with the voltage of Experimental Example 3.
[0140] Figure 7 Medium Pt / C-IrO 2 (Non Air-Water) means using Pt / C as cathode catalyst, IrO 2 As an anode catalyst, water was supplied to the anode through a water supply source, but the supply of air to the cathode through the air supply unit was cut off.
[0141] refer to Figure 7 , when 1.4V is applied, 0mA / cm is obtained 2 In this case, it was confirmed that if no...
