摘要： Fuel cells (38) have water passageways (67; 78, 85; 78a, 85a) that provide water through reactant gas flow field plates (74, 81) to cool the fuel cell. The water passageways may be vented to atmosphere (99), by a porous plug (69), or pumped (89, 146) with or without removing any water from the passageways. A condenser (59, 124) receives reactant air exhaust, may have a contiguous reservoir (64, 128), may be vertical, (a vehicle radiator, FIG. 2), may be horizontal, contiguous with the top of the fuel cell stack (37, FIG. 5), or below (124) the fuel cell stack (120). The passageways may be grooves (76, 77; 83, 84) or may comprise a plane of porous hydrophilic material (78a, 85a) contiguous with substantially the entire surface of one or both of the reactant gas flow field plates. Air flow in the condenser may be controlled by shutters (155). The condenser may be a heat exchanger (59a) having freeze-proof liquid flowing through a coil (161) thereof, the amount being controlled by a valve (166). A deionizer (175) may be used.

摘要： A PEM fuel cell power plant includes fuel cells, each of which has a cathode reactant flow field plate which is substantially impermeable to fluids, a water coolant source, and a fluid permeable anode reactant flow field plate adjacent to said water coolant source. The anode reactant flow field plates pass water from the coolant sources into the cells where the water is evaporated to cool the cells. The cathode flow field plates prevent reactant crossover between adjacent cells. By providing a single water permeable plate for each cell in the power plant the amount of water present in the power plant at shut down is limited to a degree which does not require adjunct water purging components to remove water from the plates when the power plant is shut down during freezing ambient conditions. Thus the amount of residual ice in the power plant that forms in the plates during shut down in such freezing conditions will be limited. The power plant can thus be restarted and brought up to full operating power levels quickly due to the reduced amount of ice that must be melted during startup. The power plant is thus well suited for use in powering vehicles.

摘要： Fuel cells (38) have minute water passageways (67) that provide water through one or both reactant gas flow field plates (74, 82) of each fuel cell, whereby the fuel cell is cooled convectively. The water passageways (67; 78, 85; 78a, 85a) may be vented by a porous plug (69), or by a microvacuum pump (89) that does not pump any water from the passageways, or simply vented (99) to atmosphere. A condenser (59) may have a contiguous reservoir (64); the condenser (59) may be vertical, such as a vehicle radiator (FIG. 1), or may be horizontal, contiguous with the top of the fuel cell stack (37, FIG. 5). The passageways may be grooves (76, 77; 83, 84) in the reactant gas flow plates (75, 81) or the passageways may comprise a plane of porous hydrophilic material (78a, 85a) contiguous with substantially the entire surface of one or both of the reactant gas flow field plates.

摘要： A polymer electrolyte membrane (PEM) fuel cell power plant is cooled evaporatively by a non-circulating pressurized water coolant system. The coolant system utilizes a hydrophobic porous plug for bleeding air from the coolant water while maintaining coolant back pressure in a coolant flow field of the system. Furthermore, there is a first method for identifying appropriate parameters of the hydrophobic porous plug for use with a known particular coolant system; and a second method for determining proper operating conditions for a fuel cell water coolant system which can operate with a hydrophobic porous plug closure having known physical parameters.

摘要： A media holding module to hold various granular and pelletized gas phase filtration media for filtering air. The module is comprised of two solid side plates, and a perforated end panel and four perforated wall panels disposed between the side plates. The perforated wall panels are arranged in a generally “V”-shaped configuration. The interior wall panels are contoured at the module inlet to provide aerodynamic airflow. Additionally, the interior wall panels are perforated across their entire surface areas to allow for airflow access to all filtration media in the filtration media beds. The compartment created by the wall panels may be subdivided to form sub-compartments capable of holding discrete beds of filtration media in series. The module's support members are located outside of the air stream to avoid airflow resistance and turbulence. The module further includes a flexible, reversible sealing system for sealing the module in the module housing in various configurations while preventing air bypass. The module can be used to filter other gases and/or fluids.

摘要： A PEM fuel cell (4) power plant includes a passive air vent (24) through which air separated from a cathode effluent stream can be expelled from the power plant. The air vent operates satisfactorily during ambient freezing conditions thus it is eminently suitable for use in mobile applications such as in PEM fuel cell-powered automobiles, buses, or the like. The vent is formed from a liquid antifreeze layer (40) that is disposed in a sparging tank (36) which communicates with ambient surroundings. Any water vapor in the stream can condense out of the gas-stream in the antifreeze. In order to facilitate this result, the antifreeze can be a liquid that is immiscible with water so that the condensed water will form a separate layer (38) in the sparging tank.
