Title:
SOLID ELECTROLYTIC FUEL CELL
Document Type and Number:
Japanese Patent JP3068264
Kind Code:
B2
Abstract:
PURPOSE: To prevent the crack of a solid electrolyte by a thermal distortion by using a seal material in which a specified volume of SnO2 particles having a specified particle size are added to a glass having specified values of thermal expansion coefficient and melting point.
CONSTITUTION: A seal member 6 is applied to the connecting part between a solid electrolyte 1 and a ceramic tube 3 of different member in a solid electrolytic fuel cell, and the both are sealed and fixed to each other. When a seal member in which 5-40% by volume of SnO2 particles having a particle size of 10-500μm are added to a glass having a melting point of 800-110°C is used as the member 6, the cracking of the solid electrolyte caused by a thermal distortion is prevented.
