摘要：<P>PROBLEM TO BE SOLVED: To provide a thermocouple having an insulated and waterproof surface and a diameter not larger than 0.014 mm for measuring a temperature by being inserted into a cell of a fuel cell, and to set a voltage rise per cell in the target fuel cell to be about 5V or less. <P>SOLUTION: A plus side thermocouple wire and a minus side thermocouple wire of a thermocouple is arranged linearly, and each abutting portion of the tip of the plus side thermocouple wire and the tip of the thermocouple wire facing each other is bonded by welding to form a temperature measuring junction, and polyimide is coated on the surface of the plus side thermocouple wire and the minus side thermocouple wire, to thereby form this thermocouple for the fuel cell. <P>COPYRIGHT: (C)2009,JPO&INPIT
