CONTROL OF THE POLYMER HUMIDIFYING MEMBRANE OF A FUEL CELL |
摘要 |
An electricity production system comprising a fuel cell ( 1 ) with a plurality of individual cells each comprising an anode and a cathode on either side of a solid electrolyte having optimum operating characteristics in predetermined humidification conditions. The fuel cell has a fuel gas feed circuit ( 11 ) on the anode side, a feed circuit for a combustion-supporting gas on the cathode side and at least one recycling circuit ( 12+13 ) for one of the fuel or combustive gases which recycles the gas not consumed by the fuel cell. The recycling circuit comprises a dehumidifier ( 3 ) which enables the water contained in the unconsumed gas to be removed therefrom. The recycling circuit collects a moist gas downstream from the fuel cell, passing the moist gas to the dehumidifier and returning a dehumidified gas to the feed circuit ( 11 ) upstream from the fuel cell after the gas has passed through the dehumidifier. The recycling circuit comprises a direct circuit ( 15 ) installed in parallel with the dehumidifier which taps off some of the moist gas downstream from the fuel cell and passes the moist gas into the feed circuit ( 11 ) without passing through the dehumidifier ( 3 ). Measuring means control the proportion between the moist gas and the dehumidified gas returned upstream from the cell. |
