Title:
SOLID POLYMER FUEL CELL
Document Type and Number:
Japanese Patent JP2020167064
Kind Code:
A
Abstract:
To provide a solid polymer fuel cell having an excellent catalytic activity without using a platinum-group element.SOLUTION: A fuel electrode 13 and an air electrode 14 are each composed of a thin plate-like porous metal electrode of a micro porous structure, in which permalloy fine powder is molten and binds and many fine continuous pores are evenly formed. The electrodes are 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 into 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. The electrodes have substantially the same catalytic activity as that of a fuel electrode or air electrode containing a platinum-group element.SELECTED DRAWING: Figure 3
