PROBLEM TO BE SOLVED: To provide a fuel cell condition easily detecting device detecting the conditions of fuel cell stack with high accuracy, for example, the temperature and the like, related to the state of electric power generation or the like. SOLUTION: A cooling liquid flow path 36, arranged between a cooling liquid flow path 20a and a cooling liquid flow path 20b, is installed at a limited part of the part, for example, at the central part of the width of the cell, where a fuel gas flow path and an air flow path are overlapping ( a part enabled to generate electric power). The cooling liquid path 36 is connected to a cooling liquid circulating circuit 51 in parallel with the cooling liquid flow path 20a and the cooling liquid flow path 20b, through cooling liquid flow paths 37, 38 and cooling liquid circulating circuits 53, 54. A temperature sensor 55, detecting the temperature of the cooling liquid at the neighboring area of the cooling liquid flow path 37 of exhaust side, is installed to the cooling liquid circulating circuits 53, and a temperature sensor 56, detecting the temperature of the cooling liquid flowing in the cooling liquid circulating circuits 54, is installed to the cooling liquid circulating circuits 54 of supply side. |
