Abstract

Official abstract text for this publication.

A metal porous body includes a flat plate shape and having continuous pores, a framework of the metal porous body including an alloy layer containing nickel and at least one of chromium and tin, a cobalt layer being formed on a surface of the alloy layer.

First claim

Opening claim text (preview).

1 . A metal porous body having a flat plate shape and having continuous pores, a framework of the metal porous body having an alloy layer containing nickel and at least one of chromium and tin, a cobalt layer being formed on a surface of the alloy layer. 2 . The metal porous body according to claim 1 , wherein the cobalt layer has an average film thickness of more than or equal to 1 μm. 3 . The metal porous body according to claim 1 , wherein the alloy layer is a NiSn alloy containing Ni as a main component, a NiCr alloy containing Ni as a main component, or a NiSnCr alloy containing Ni as a main component. 4 . The metal porous body according to claim 1 , wherein a shape of the framework is a three-dimensional network structure. 5 . The metal porous body according to claim 1 , wherein the metal porous body has a porosity of more than or equal to 60% and less than or equal to 98%. 6 . The metal porous body according to claim 1 , wherein the metal porous body has an average pore diameter of more than or equal to 50 μm and less than or equal to 5000 μm. 7 . The metal porous body according to claim 1 , wherein the metal porous body has a thickness of more than or equal to 500 μm and less than or equal to 5000 μm. 8 . A solid oxide fuel cell comprising the metal porous body according to claim 1 , as a gas diffusion layer. 9 . A method for producing a metal porous body, comprising: preparing a porous body base material having a flat plate shape and having continuous pores; and plating cobalt on an entire surface of a framework of the porous body base material, the framework of the porous body base material having an alloy layer containing nickel and at least one of chromium and tin. 10 . The method for producing the metal porous body according to claim 9 , wherein a shape of the framework of the porous body base material is a three-dimensional network structure.
