摘要： A fuel cell comprising a gas-permeable and electrically conducting support substrate having a fuel gas passage formed therein; a fuel-electrode layer formed on said substrate; a solid electrolytic layer formed on said support substrate so as to cover said fuel-electrode layer and containing ZrO2 in which rare earth elements are existing in the form of solid solutions; and an oxygen-electrode provided on the solid electrolytic layer so as to face said fuel-electrode layer; wherein said support substrate is formed of a metal of the iron family and/or an oxide of a metal of the iron family, and a rare-earth oxide containing at least one kind of element selected from the group consisting of Y, Lu, Yb, Tm, Er, Ho, Dy, Gd, Sm and Pr. The invention brings a coefficient of thermal expansion of the support substrate close to that of the solid electrolytic layer, and prevents a reduction in the performance of the solid electrolyte caused by the diffusion of elements from the support substrate.

摘要： Low thermal expansion ceramics contains a cordierite crystal phase, wherein a phase of a crystalline compound containing at least one element selected from the group consisting of an alkaline earth element other than Mg, a rare earth element, Ga and In, is precipitated in the grain boundaries of said crystal phase, said ceramics has a relative density of not smaller than 95%, a coefficient of thermal expansion of not larger than 1x10 -6 /° C. at 10 to 40° C., and a Young's modulus of not smaller than 130 GPa. That is, the ceramics has a small coefficient of thermal expansion, is deformed very little depending upon a change in the temperature, has a very high Young's modulus and is highly rigid and is resistance against external force such as vibration. Accordingly, the ceramics is very useful as a member for supporting a wafer or an optical system is a lithography apparatus that forms high resolution circuit patterns on a silicon wafer.
