GASKET FOR MOLTEN CARBONATE FUEL CELL HAVING A OXIDE BARRIER LAYER FOR THE PREVENTION OF ELECTROLYTE MIGRATION

摘要

The present invention relates to a gasket for an MCFC in direct contact with a molten carbonate electrolyte constituting a wet seal portion of a stack in a manifold seal portion of an external manifold type MCFC stack, The partial gasket has a structure in which a blocking layer is formed to physically block the movement of the molten carbonate electrolyte between the partial gasket and the partial gasket, Or a green sheet layer, and is manufactured by simultaneous sintering of the partial oxide felt bonded body and the barrier layer during the gasket sintering process.
