Molten carbonate fuel cell and method of manufacturing retaining material for electrolyte body of molten carbonate fuel cell

摘要

A molten carbonate fuel cell comprises a fuel electrode, an oxidizing agent electrode, and an electrolyte body prepared by impregnating a porous body including a retaining material and a reinforcing material with an electrolyte containing an alkali carbonate. The retaining material consists essentially of alpha -lithium aluminate ( alpha -LiAlO2) having at most 0.60 DEG of a half value width of (104) peak in an X-ray powder diffractometry.
