Abstract

Official abstract text for this publication.

The present invention is a method for producing a porous metal body or a method for producing an electrode catalyst, which is capable of simplifying the production process and improving the production efficiency by not requiring a step of immersion in an acid treatment solution. A method for producing a porous metal body according to the present invention comprises: a step for forming a metal resin-containing layer, which contains a metal and a resin that has a lower melting point than the metal, on a base; and a step for obtaining a porous metal body by subjecting the metal resin-containing layer to a heat treatment, thereby sintering the metal and removing the resin from the metal resin-containing layer.

First claim

Opening claim text (preview).

What is claim is: 1 . A method for producing a porous metal body, comprising the steps of: forming a metal-resin-containing layer containing a metal and a resin on a base, a melting point of the resin being lower than that of the metal; and heat-treating the metal-resin-containing layer, thereby sintering the metal and removing the resin from the metal-resin-containing layer, to obtain the porous metal body. 2 . The method according to claim 1 , wherein in the step of forming the metal-resin-containing layer, a metal layer containing the metal and a resin layer containing the resin are stacked to form the metal-resin-containing layer. 3 . The method according to claim 1 , wherein in the step of forming the metal-resin-containing layer, the metal-resin-containing layer is formed by at least one of sputtering and vapor deposition. 4 . A method for producing an electrode catalyst, comprising the steps of: forming a metal-resin-containing layer containing a metal catalyst and a resin on a base, a melting point of the resin being lower than that of the metal catalyst; and heat-treating the metal-resin-containing layer, thereby sintering the metal catalyst and removing the resin from the metal-resin-containing layer, to obtain a porous electrode catalyst. 5 . The method according to claim 4 , wherein in the step of forming the metal-resin-containing layer, a metal layer containing the metal catalyst and a resin layer containing the resin are stacked to form the metal-resin-containing layer. 6 . The method according to claim 4 , wherein in the step of forming the metal-resin-containing layer, the metal-resin-containing layer is formed by at least one of sputtering and vapor deposition. 7 . The method according to claim 4 , wherein a gas diffusion layer is used as the base.
