Title:
電気分解装置の陽極及び陰極の製造方法
Document Type and Number:
Japanese Patent JP7262739
Kind Code:
B2
Abstract:
To provide an electrolyzer provided with an anode and a cathode having excellent catalytic activity regardless of a low platinum group metal content, capable of efficiently performing electrolysis by using the anode and the cathode, and generating a large amount of hydrogen gas in a short time.SOLUTION: An anode 11 and a cathode 12 forming an electrolyzer 10 are formed of at least one kind of a small amount of platinum group metal selected from various platinum group metals and at least two kinds of transition metals selected from various transition metals. A prescribed pore formation material is added to a metal fine powder mixture obtained by uniformly mixing and dispersing platinum group metal fine powders obtained by finely pulverizing the selected at least one kind of platinum group metal and transition metal fine powders obtained by pulverizing the selected at least two kinds of transition metals, and a prescribed binder, the metal fine powder mixture added with the pore formation material is molded into a sheet shape with a prescribed area, and the metal fine powder molding molded into the sheet shape with the prescribed area is degreased and sintered so as to be sheet-shaped electrodes with a microporous structure formed with many fine pores.SELECTED DRAWING: Figure 1
