Abstract
This cathode-side humidification tankalso functions as a coolant tank. The water in the cathode-side humidification tankcools the fuel celland returns to the cathode-side humidification tank. In the foregoing situations where the fuel cellis low in temperature, such as during the startup of the fuel cell system, the coolant warmed by the heat exchanger HEXcan also be supplied to the fuel cellto warm up the fuel cell. Moreover, a coolant channelfor supplying a coolant to a cooling plateprovided in the fuel cellis in connection with a heat exchanger HEXwhich is formed in an anode-side humidification tank. Consequently, the coolant even plays the role of maintaining the cathode-side humidification tankand the anode-side humidification tankin almost the same temperatures.
