ABSTRACT:
A porous matrix of lithium aluminate particles for molten alkali metal carbonates electrolytes having about 5 to about 50 volume percent, based upon the volume of the solids, of electrically non-conductive, active electrolyte compatible fibers having an average diameter of about 1 to about 50 microns and an average length greater than about 5 times the average diameter. Such matrices reduce matrix cracking upon loading with molten carbonates active electrolyte and provide high surface area over long term fuel cell operation.
