摘要： The fuel cell humidifying system is to prevent freezing and clogging of a water permeable type humidifier by providing a gas passage switching device for changing the gas flow paths communicating with the humidifier. To direct the flow of dry air exiting from the supercharger to the exhaust passage in the humidifier, the gas passage switching device includes a first three-way valve, a second three-way valve, a flow adjusting valve and a sweep piping. In this system, water vapor in the humidifier which causes freezing can be swept off by flowing dry air through the exhaust gas passage in the humidifier, and therefore, clogging caused by ice particles which plug up the pores of the hollow thread membrane in the humidifier can be prevented.

摘要： A humidifying system for a fuel cell, the system producing a highly wet air by allowing dry air to pass through a water permeable humidifier, and supplying the highly wet gas to a fuel cell, wherein the humidifying system comprises a supercharger between an inlet for introducing gas into the fuel cell and an outlet for releasing gas from the humidifier. Since the pressure at the inlet of the supercharger is lower than the pressure at the outlet, the flow velocity at the inlet is higher than the flow velocity at the outlet. Therefore, the flow velocity of the dry air which flows inside the humidifier can be increased so as to be higher than the flow velocity in the case where the supercharger 3 is provided between the inlet for introducing gas into the fuel cell and a gas intake opening. Accordingly, the efficiency of humidification is improved, and the sizes of the humidifier and the supercharger can be reduced.

摘要： A humidifier includes a housing that accommodates bundles of a large number of water permeable hollow fiber membranes arranged along the longitudinal direction of the housing. Two different gasses having different moisture contents pass through outside and inside of the bundle of the hollow fiber membranes separately to exchange their moistures through the hollow fiber membranes resulting in the dry gas of lesser moisture content being humidified. A heating or temperature adjuster is provided to maintain the temperature of the exhaust gas introduced to the humidifier or the bundles of hollow fiber membranes substantially at a temperature of a fuel cell in operation.
