Title:
SOLID ELECTROLYTE FILM OF FUEL CELL AND MANUFACTURE THEREOF
Document Type and Number:
Japanese Patent JPH0652869
Kind Code:
A
Abstract:
PURPOSE: To efficiently manufacture a compact film of solid electrolyte required to a solid electrolyte fuel cell (SOFC).
CONSTITUTION: A compact film 2 of electrolyte for blocking pores in an electrode base 1 and a frame-sprayed film 3 of electrolyte formed by frame spraying method are sequentially provided on the electrode base 1. A slurry of particles of stabilized zirconia (YSZ) is previously applied to the surface of an electrode serving as a cell base and is sintered to block the pores, and the film of electrolyte is formed thereafter by frame spraying, whereby a compact film of solid electrolyte can be obtained.
