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.
Claims14
A fuel cell assembly comprising:
- cells having gas passages,
- a holding means,
- a fixing member for fixing the cells to the holding means, the fixing member being arranged between the peripheries of the ends on one side of said cells and the holding means, a sealing member being arranged between the peripheries of the cells and the holding means so as to cover the fixing member, the softening temperature of the fixing member being higher than 1000° C., and the softening temperature of the sealing member being from 700 to 1000° C., wherein the fixing member and sealing member have different compositions;
- wherein said sealing member is a crystalline or amorphous ceramic having a low degree of crystallinity and containing SiO2, ZnO, B2O3, and RO (R is an alkali earth metal) and the fixing member is a crystalline or amorphous ceramic having a higher degree of crystallinity and containing SiO2, ZnO, B2O3, and RO (R is an alkali earth metal).
