Abstract : A product-water management system removes steam produced by the reaction of hydrogen and oxygen in a fuel cell, by circulating a hydrogen stream, containing the steam, from the fuel cell to a condenser where the water is liquified and collected in a sump. A continuously operating pump forces water and/or hydrogen from the sump through a transfer line to a water storage tank. Hydrogen is vented back to the condenser from the storage tank through a vent line concentrically mounted within the transfer line. A tank drain on the storage tank allows hydrogen to be purged between missions. (Author)
