Method of manufacturing an insulating component for a high-temperature fuel-cell and high-temperature fuel-cell

摘要

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 mu thick water-containing layer (20); (b) converting the layer (20), preferably at 80-140 degrees C for 2-10 hrs., to form a rubber-like layer (26); (c) burning out the binder from the layer (26), preferably at 200-600 degrees C for 1-4 hrs.; (d) consolidating the layer (26), preferably at 1400-1600 degrees C for NOTGREATER 60 hrs.; and (e) subjecting the consolidated layer (30) to machining to the component dimensions and dense sintering, preferably at 1500-1800 degrees C for NOTGREATER 60 hrs. Also claimed is a high temperature fuel cell with an insulating component made by the above process.
