(JP11135138-A)      Production of an insulating ceramic component (8) for a high temperature fuel cell is carried out by (a) casting a dispersion of the ceramic material and a water soluble binder to form a preferably 500-800 thick water-containing layer (20); (b) converting the layer (20), preferably at 80-140C for 2-10 hrs., to form a rubber-like layer (26); (c) burning out the binder from the layer (26), preferably at 200-600C for 1-4 hrs.; (d) consolidating the layer (26), preferably at 1400-1600C for 60 hrs.; and (e) subjecting the consolidated layer (30) to machining to the component dimensions and dense sintering, preferably at 1500-1800C for 60 hrs. Also claimed is a high temperature fuel cell with an insulating component made by the above process.    USE -   Especially for producing an insulating magnesium aluminate spinel frame for positioning between the adjacent interconnector plates of a high temperature fuel cell stack.    ADVANTAGE -   The process is simpler and less expensive than prior art processes involving direct deposition on an interconnector plate or machining of a pressed and sintered plate.
