Abstract: A fuel cell assembly in which ends on one side of the cells forming gas passages are gas-tightly fixed to a holding means. Between the peripheries of the ends on one side of the cells and the holding means, there are arranged a fixing member for fixing the cells to the holding means and a sealing member for accomplishing a gas-tight sealing between the ends on one side of the cells and the holding means. The fixing member has a softening temperature of not lower than 1000° C. and the sealing member has a softening temperature of from 700 to 1000° C.

Abstract: A solid oxide fuel cell comprising an electrically conducting electrode-support substrate, an inner electrode layer, a solid electrolyte layer, an outer electrode layer and an interconnector, wherein said electrode-support substrate includes a flat plate having two flat surfaces which are in parallel with each other and forming a plurality of gas flow passages therein, and curved portions located at both ends of said flat plate, and said outer electrode layer is laminated on the solid electrolyte layer so as to be opposed to the other surface of said flat plate where the interconnector is not provided but so as not to be opposed to said curved portions. The solid oxide fuel cell features a small voltage drop, an increased output density, and is easily produced exhibiting stable characteristics.

Abstract: A molding method of ceramic body comprising the following steps of:preparing a ceramic slurry by adding, to ceramic raw material powders, a solvent, organic dispersant and caking agent and mixing them altogether; casting said ceramic slurry into a mold; cooling it to a temperature lower than the melting point of said caking agent; and taking it out of the mold.This molding method is capable of dissolving cracking generation during releasing the ceramic body from a mold, facilitating machining, decreasing the binder amount of organic compounds, diminishing a firing shrinkage and obtaining a higher dimension accuracy.
