Abstract: Electrolyte Matrix For Molten Carbonate Fuel Cells Thru-cracks in the electrolyte retaining matrix of a molten carbonate fuel cell caused by thermal cycling of the cell between operating and room temperature are prevented by an improved matrix comprising a major proportion of submicron support particles and a minor proportion, perhaps only a few percent, of much larger crack attenuator particles. In one embodiment wherein the electrolyte is to be a binary lithium potassium carbonates composition, the matrix comprises 90 volume percent submicron lithium aluminate support particles and 10 volume percent alumina crack attenuator particles with an average size of 100 microns.
