Title: High performance electrolytes for MCFC

Abstract

A carbonate electrolyte of the Li/Na or CaBaLiNa system. The Li/Na carbonate has a composition displaced from the eutectic composition to diminish segregation effects in a molten carbonate fuel cell. The CaBaLiNa system includes relatively small amounts of Ca.sub.2 CO.sub.3 and BaCO.sub.3, and preferably of equimolar amounts. The presence of both Ca and BaCO.sub.3 enables lower temperature fuel cell operation.
