FABRICATION METHOD OF SUBSTRATE-SUPPORTED COATING LAYERS BY USING TAPE CASTING FILM SHEET

摘要

PURPOSE: A manufacturing method of a support type coating film is provided to easily manufacture a green film type sheet and to easily and simply form the same on a support by only one tap casting. CONSTITUTION: A manufacturing method of a support type coating film comprises a step of forming a support; a step of forming a green sheet for a coating film on a releasing film; a step of attaching a green sheet on the support; a step of removing the releasing film from a laminate which consists of a mold releasing film, green sheet, and a support; and a step of co-sintering the support and the laminate of the green sheet. The final thickness of the coating film is 0.1-900μm. The sintered density of the coating film is 30% or more. The support is a fuel electrode or air electrode.
