Zusammenfassung: | PURPOSE:To acquire an electrode having a reinforcement wire net only on one side in a simple method, by dissolving an organic binder in a mixed solution including an organic solvent, mixing and kneading the resultant binder solution and a metallic powder to make into a slurry, spreading the slurry on one side of a reinforcement wire net to hold the slurry, and baking up the slurry on the wire net into a porous body in a plate form. CONSTITUTION:In a mixed solvent consisting of water, methyl alcohol, isopropyl alcohol, and a nonionic surface active agent, methyl cellulose is dissolved, and the resultant binder solution and nickel powder are mixed and stirred at a reduced pressure, to make the powder into a slurry. After the resultant slurry S is put into a holder hopper 5, the slurry S is spread on the upper side of a wire net 1. After the wire net 1 holding the slurry S is removed from the slurry holder hopper and dried up, a filter paper 6 is removed from the wire net 1, and then the wire net 1 is placed in an electric furnace. After the air in the furnace is replaced with hydrogen, the slurry S is maintained in a steam flow and baked up into a porous body. |
