Title:
METAL-SUPPORTED SOLID OXIDE FUEL CELL AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/045302
Kind Code:
A1
Abstract:
In order to provide a solid oxide fuel cell readily ensuring porosity and having excellent deformation resistance at high temperatures so as to have advantageous large-scalability, embodiments of the present invention provide a metal-supported solid oxide fuel cell comprising a sintered body of metal powder formed as polygonal grains having an aspect ratio of 0.5-2.0. The metal-supported solid oxide fuel cell, according to one embodiment of the present invention, comprises: a metal support; a fuel electrode provided on the metal support; an electrolyte provided on the fuel electrode; and an air electrode provided on the electrolyte, wherein the metal support comprises a sintered body of a metal alloy powder comprising polygonal grains having an aspect ratio of 0.5-2.0.
