Thin film ceramic proton conducting electrolyte

摘要

A thin film ceramic proton conducting electrolyte assembly ( 10 ) is provided having a includes a nanoporous, copper supporting substrate ( 11 ), a temporary substrate pore filler material ( 12 ), and a ceramic electrolyte layer ( 13 ) positioned upon the substrate ( 11 ). The ceramic electrolyte layer may be made of a yttrium doped strontium zirconate. To produce the electrolyte the substrate pores ( 14 ) are filled with the pore filler material to provide a smooth surface upon which the electrolyte layer is deposited. The filler material is then removed from the pores and the substrate and electrolyte layer are annealed.
