A ceramic substrate for an electrochemical element that includes a ceramic layer and a high-thermal-expansion-coefficient material layer that is laminated on the surface of the ceramic layer. The high-thermal-expansion-coefficient material layer has a higher coefficient of thermal expansion than the ceramic layer, and applies compressive stress to the ceramic layer.

Ceramic substrate for electrochemical element, manufacturing method therefore, fuel cell, and fuel cell stack

A glass ceramic multilayer circuit board uses Ag as a conductive material, in which oxidation and diffusion of silver are suppressed. The glass ceramic multilayer circuit board is formed by stacking glass ceramic layers and conductor layers, and then simultaneously burning the layered product. The glass ceramic layers are made of a glass ceramic insulating material which is composed of a glass component and a ceramic component, and to which a metal powder of Cu, Ni or the like is added.
