ABSTRACT:
A method of forming an electrolyte matrix for a carbonate fuel cell. An .alpha.-LiAlO.sub.2 ceramic is mixed in an aqueous solvent having a citric acid dispersant and deflocculated using a high energy attrition milling. The deflocculated mixture is added to an alcohol/glycerol aqueous binder system to form a slurry which is degassed and then tape cast to form the matrix.
