<P>PROBLEM TO BE SOLVED: To solve the problem that a K-type thermocouple has degraded in a reducing atmosphere of hydrogen etc. in a short time. <P>SOLUTION: In this thermocouple type temperature sensor, a nickel-chromium alloy is used as before as KP (a positive electrode) of a thermocouple, a K-type sheathed thermocouple to be used for measuring the temperature of and controlling gases having hydrogen as a principal component of temperatures between 600-1000°C to be used for a gas cracking device of solid high molecular fuel cells and as a fuel in solid oxide fuel cells. A nickel-copper alloy containing copper of 1.9-3.0% is used as KN (a negative electrode). <P>COPYRIGHT: (C)2006,JPO&NCIPI |
