Title:
ELECTRODE AND MANUFACTURING METHOD THEREOF
Document Type and Number:
Japanese Patent JP2020167041
Kind Code:
A
Abstract:
To provide an electrode which can fabricated at low cost without using a platinum-group element and which can exhibits a catalytic activity substantially at the same level as that of a platinum-group element-containing electrode.SOLUTION: An electrode 10 is composed of a thin plate-like porous metal electrode of a micro porous structure, in which permalloy fine powder melts and binds, and many fine continuous pores are evenly formed; the continuous pores are defined by a permalloy molten material which permalloy fine powder melts and binds into. The electrode is arranged by the steps of: uniformly mixing and dispersing a predetermined binder in permalloy fine powder prepared by finely pulverizing Fe-Ni permalloy and in parallel, uniformly mixing and dispersing a predetermined pore-forming material therein to make a permalloy fine powder mixture; molding the permalloy fine powder mixture having the binder and pore-forming material mixed in the permalloy fine powder in a thin plate-like form having a given area; and then, degreasing and sintering the resultant permalloy fine powder mixture mold shaped in the thin plate-like form.SELECTED DRAWING: Figure 1
