    摘要: In an automated process for deaerating and purifying both the water which is recirculated in a coolant loop through a stack of fuel cells and the make-up water for the coolant loop, a portion of the water from the coolant loop is blown down into a deaerator water reservoir to which make-up water is added by condensing water from the fuel cell stack reactant gas streams into a deaeration column disposed above the reservoir. The blowdown provides some of the heat for deaeration; and the amount of blowdown is controlled as a function of the amount of make-up water added to the coolant loop by sensing the location of a steam/liquid interface within the deaeration column. Water is withdrawn from the reservoir, purified, and then introduced into the coolant loop at a rate sufficient to maintain the desired amount of water circulating in the coolant loop.

    摘要: A separator scrubber (58) and isolation loop (78) decontaminates a fuel reactant stream of a fuel cell (12). Water passes over surfaces of an ammonia dissolving means (61) within the scrubber (58) while the fuel reactant stream simultaneously passes over the surfaces to remove contaminants from the fuel reactant into the water. An accumulator (68) collects the separated contaminants and water, and an isolation loop pump (84) directs flow of the separated contaminant stream through the isolation loop (78). A heat exchanger (86) and an ion exchange bed (88) modify the heat of, and remove contaminants from, the separated contaminant stream, and the isolation loop (78) directs the decontaminated stream back onto the packed bed (62)-. Separating contaminants from the fuel reactant stream and then isolating and concentrating the separated contaminants within the ion exchange bed (88) minimizes cost and maintenance requirements.

    摘要: A liquid-gas separator assembly is used in separating gas bubbles from a liquid coolant which liquid coolant is used in a polymer electrolyte membrane (PEM) fuel cell power plant. The assembly includes a cylindrical housing containing a central tube which is surrounded by an annular chamber. The annular chamber is defined by the outer surface of the central tube and the inner surface of the cylindrical housing. An inlet line injects a stream of the coolant from the fuel cell stack area of the power plant into the bottom of the central tube in a tangential flow pattern so that the coolant and gas bubble mixture swirls upwardly through the central tube. The swirling flow pattern of the coolant and gas bubble mixture causes the gas bubbles to separate from the liquid coolant so that the gas in the mixture will migrate to the central portion of the swirl tube and the liquid component of the mixture will centrifugally migrate to the inner wall of the swirl tube. The gaseous component of the separated mixture is then expelled from the housing through an outlet in the upper portion of the housing, and the coolant liquid descends through the annular chamber to the bottom of the housing where the coolant liquid will be returned to the cell stack area of the power plant. The gas bubbles may include reactant from either the cathode or the anode. The separator of this invention is particularly useful in mobile applications since it is less sensitive to vehicular acceration forces.

    摘要: Method and apparatus are provided for removing contaminants from a hydrogen processor feed stream, as in a fuel cell power plant (110). Inlet oxidant (38), typically air, required by a catalytic hydrogen processor (34) in a fuel processor (14) for a fuel cell stack assembly (12) in the power plant (110), may contain contaminants such as SO2 and the like. A cleansing arrangement, which includes an accumulator/degasifier (142, 46) acting as a scrubber, and possibly also a water transfer device (118), receives the inlet oxidant and provides the desired cleansing of contaminants. Water in the water transfer device and in the accumulator/degasifier serves to dissolve the water-soluble contaminants and cleanse them from the oxidant stream. The cleansed oxidant stream (138′) is then delivered to the hydrogen processor and to the fuel cell assembly, with minimal inclusion of detrimental contaminants such as sulfur.

    摘要: A fine pore enthalpy exchange barrier is disclosed for use with a fuel cell power plant. The barrier includes a flexible support matrix that defines pores and a liquid transfer medium that fills the pores creating a gas barrier. An inlet surface of the fine pore enthalpy exchange barrier is positioned in contact with a process oxidant inlet stream entering a fuel cell power plant, and an opposed exhaust surface of the barrier is positioned in contact with an exhaust stream exiting the plant so that water and heat exchange from the exhaust stream directly into the process oxidant inlet stream to heat and humidify the stream as it enters the plant. The flexible support matrix defines hydrophilic pores having a pore-size range of about 0.1-100 microns and results in a bubble pressure that is greater than 0.2 pounds per square inch. The liquid transfer medium may include water, aqueous salt solutions, aqueous acid solutions, or organic antifreeze water solutions. The fine pore enthalpy exchange barrier may be disposed within a structure of a direct mass and heat transfer device of the plant in fluid communication with the process oxidant inlet and plant exhaust streams so that the structure and barrier cooperate to restrict bulk mixing of the inlet and exhaust streams, and water and heat transfer through the transfer medium from the plant exhaust stream into the process oxidant stream entering the plant.

    摘要: In order to achieve good stack water chemistry and minimize corrosion in a fuel cell stack water cooling loop, the oxygen concentration in the water must remain within a relatively narrow range. Stacks using steam separators produce water in the separators which is relatively devoid of oxygen. Makeup water is used to replace the steam lost from the separator, which makeup water is relatively rich in oxygen. The flow rates of the makeup water and steam separator water are controlled to produce a proper oxygen concentration in the recirculated coolant water. Some of the makeup water will be added directly into the steam separator so that it will be stripped of oxygen and the rest will be added subsequent to the steam separator.

    摘要: In a process for deaerating and purifying both the water which is recirculated in a coolant loop through a stack of fuel cells and the make-up water for the coolant loop, a portion of the water from the coolant loop is blown down into a deaerator water reservoir to which make-up water is added as required by the coolant loop. Water is withdrawn from the reservoir, purified, and then introduced into the coolant loop at a rate sufficient to maintain the desired amount of water circulating in the coolant loop. The blowdown provides some of the heat for deaerating the water; and the rate of blowdown flow into the reservoir is sufficient to maintain an acceptable level of impurities in the recirculating coolant loop water. Preferably, the blowdown flow rate is controlled as a function of the amount of make-up water required to be added to the coolant loop.
