Title:
POROUS BODY, ELECTROCHEMICAL CELL, AND METHOD FOR PRODUCING POROUS BODY
Document Type and Number:
WIPO Patent Application WO/2020/179693
Kind Code:
A1
Abstract:
In a porous body comprising a porous electrically conductive base material and a metal coating film formed on the porous electrically conductive base material, both of the reduction of the amount of a metal to be used for the formation of the metal coating film and the prevention of the formation of an oxide coating film between the porous electrically conductive base material and the metal coating film can be achieved. A porous body which comprises a porous electrically conductive base material having communicating voids and a skeleton forming the voids and a metal coating film arranged on at least a portion of the surface of the skeleton, wherein the porosity of the porous electrically conductive base material is 10% or more, 70% by mass of more of the metal coating film exists in a region lying within 30% from one surface of the porous body as observed in the thickness direction, and the thickness of an oxide coating film between the skeleton and the metal coating film is 2 nm or less in at least a part of the oxide coating film.
