MATRIS FOR ATT KVARHALLA EN ELEKTROLYT AV SMELT KARBONAT-TYP I EN BRENSLECELL |
摘要 |
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. |
