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.

Abstract: Molten Carbonate Fuel Cell Matrix Tape and Assembly Method A matrix material for a molten carbonate fuel cell is described which is flexible, pliable and has rubberlike compliance at room temperature. The matrix has three components comprising fine inert particulate material, larger crack attenuating ceramic particulate material, and an organic polymeric binder. A process of assembling a molten carbonate fuel cell utilizing the compliant matrix material is also described. The compliant matrix material is inserted into a molten carbonate fuel cell stack utilizing fuel cell anodes with sufficient porosity to contain excess electrolyte. The fuel cell is heated up to a temperature sufficient to remove the polymer binder and cause a portion of the electrolyte material present in the anode to wick into the matrix to substantially fill it completely.
