FUEL GAS PIPE FOR SOLID OXIDE FUEL CELL, THE SOLID OXIDE FUEL CELL, AND USAGE METHOD OF THE FUEL GAS PIPE

摘要

PPROBLEM TO BE SOLVED: To provide a gas supplying/exhausting method which does not lose flexibility of design and sealing properties, capable of obtaining proper and a long-termed calking resistant property, without using noble metals, when supplying dry hydrocarbon gas to a solid oxide fuel cell. PSOLUTION: The fuel gas pipe for the solid oxide fuel cell is made of heat-resistant alloy, and used for supplying or exhausting gas, containing hydrocarbon or carbon monoxide, to or from the solid oxide fuel cell operation at a temperature range of 600C to 1,000C. The inner surface of the gas pipe or the neighboring area of the front surface thereof has an alumina layer. PCOPYRIGHT: (C)2005,JPO&NCIPI
