Abstract
The present application relates to a method of manufacturing an anode support of a solid oxide fuel cell and an anode support of a solid oxide fuel cell, and may improve performance and durability of the fuel cell by improving an interfacial property between the anode support and an electrolyte.
Claims9
An anode support of a solid oxide fuel cell comprising:
- a structure of a metal and an inorganic oxide having oxygen ion conductivity, the structure having a treated portion and a non-treated portion, the treated portion including a surface of the anode support that contacts an electrolyte, the structure being prepared by a press and sinter operation,
- wherein the surface of the treated portion that contacts the electrolyte has a plurality of pores such that the surface of the treated portion has a porosity of from 5% to 50%, each of the pores having a size from 0.1 micrometers to 1 millimeter, and
- wherein the treated portion occupies from 5% to 50% of a total volume of the anode support and comprises the inorganic oxide, and
- wherein the treated portion is a portion that has been treated by removing the metal using an acid.
