Title:
THIN FILM TYPE SOLID OXIDE FUEL CELL HAVING STRESS RELAXATION STRUCTURE USING POROUS SILICON AND METHOD FOR MANUFACTURING THE SAME
Document Type and Number:
Japanese Patent JP2023147130
Kind Code:
A
Abstract:
To provide a thin film type solid oxide fuel cell having a stress relaxation structure of a membrane edge.SOLUTION: A solid oxide fuel cell includes: a silicon substrate; an electrolyte film formed on a first surface of the silicon substrate; a first electrode formed on at least part of the first surface of the electrolyte film; a recess portion formed so as to expose, from a second surface of the silicon substrate that is an opposite surface of the first surface, part of the second surface that opposes the first electrode that is an opposite surface of the first surface of the electrolyte film; and a second electrode formed on the second surface on which at least the electrolyte membrane is exposed. The silicon substrate includes a porous portion formed by porosity at least in the vicinity of an edge of the recess portion.SELECTED DRAWING: Figure 1
