ELECTROLYTE LAYER HAVING A PATCHWORK-TYPE NANOPOROUS GRAIN BOUNDARY AND A METHOD OF PREPARATION THEREOF

摘要

Gadolinium-doped cerium oxide slurries used to form a patchwork type surface structure with nanoporous grain boundary prepared by mixing gadolinium-doped cerium oxide and a polymer binder to form a first mixture; wet-atomizing the first mixture under a pressure of at least 100 MPa to obtain a second mixture; coating the second mixture to a substrate to form a coated substrate; and sintering the coated substrate. The patchwork type structure is a polygonal or honeycomb structure having a size of from 0.1 μm to 3 μm.
