PURPOSE:To obtain a highly reliable fuel cell, in which control of the flow amount of a refrigerant at low load, supply and exhaustion of a fuel or an oxidant gas, and work of joining cooling tubes and each cooling mother tube can be performed in an excellent manner, by positioning the cooling mother tubes of the cooling systems separately in different manifolds so as to enlarge the distance between the cooling mother tubes. CONSTITUTION:A cooling system is divided into two systems, the first cooling system consisting of a cooling mother tube 5A and cooling tubes 4A and the second cooling system consisting of a cooling mother tube 5B and cooling tubes 4B. The cooling mother tubes 5A and 5B of the first and the second cooling systems are separately positioned in different manifolds 2 which cover side surfaces which face to one another. Besides, the cooling tubes 4A and 4B of the first and the second cooling systems are alternately positioned over a cooler cell 3. In the figure, the symbol 8 represents a refrigerant which circulates through the cooling system. Therefore, when one of the cooling systems becomes out of order, cooling can be performed with the other cooling system. As a result, a battery can be prevented from coming to have unusually high temperature. |
