고체산화물 연료전지의 제조방법

Fabrication method of solid oxide fuel cell

Abstract

PURPOSE: A manufacturing method of solid oxide fuel cell is provided to minimize contraction difference between thin films by minimizing organic components in a slurry composition, and to improve battery performance by increasing adhesion of a dense thin film to the porous thin film. CONSTITUTION: A manufacturing method of solid oxide fuel cell comprises: a step of manufacturing a porous support by mono-axially press-molding powder for forming electrode, and drying the product; a step of forming a solid electrolyte laminate layer by spraying slurry composition for forming solid electrolyte on the porous support; a step of co-sintering the porous support and the solid electrolyte laminate layer. The slurry composition comprises 5-20 parts by weight of polyvinylbutyral, and 100-500 parts by weight of a mixture of alcohol/organic solvent based on 100.0 parts by weight of ceramic powder for the solid electrolyte.
