<P>PROBLEM TO BE SOLVED: To provide a cooling device of a fuel cell capable of diluting a fuel gas mixed in a circulation passage of the coolant to drain it with low concentration, and of keeping the concentration of a gas in the coolant at a low level by exhausting the gas conventionally allowed to stay in a heat exchanger or the circulation passage of the coolant as needed without requiring mainteners. <P>SOLUTION: In this cooling system of a fuel cell 1, the coolant is circulated between the inside of the fuel cell 1 and the heat exchanger 2. The gas mixed in the coolant is separated and exhausted by mixing it with air supplied to the fuel cell1 1 or the exhaust air from the fuel cell 1. Since the fuel gas mixed in the circulation passage of the cooling can be exhausted by mixing it with the supplied air, the fuel gas in the exhaust gas of the fuel cell can be exhausted at low concentration by diluting it. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
