摘要： A fuel cell power plant (36) has vertical fuel cells (102) each sharing a half of a hybrid separator plate (100) which includes a solid fuel flow plate (105) having horizontal fuel flow channels (106) on one surface and coolant channels (108) on an upper portion of the opposite surface, bonded to a plain rear side of a porous, hydrophilic oxidant flow field plate (115) having vertical oxidant flow channels (118). Coolant permeates through the upper portion of the porous, hydrophilic oxidant flow field plates and enters the oxidant flow channels, where it evaporates as the water trickles downward through the oxidant flow field channels, thereby cooling the fuel cell.

摘要： Fuel cell systems (100, 400) and related methods involving accumulators (106, 200, 300, 406) with multiple regions (R1, R2; R1′, R2′) of differing water fill rates are provided. At least one accumulator region with a relatively more-rapid fill rate (R2; R2′) than another accumulator region (R1; R1′) is drained of water at shutdown under freezing conditions to allow at least that region to be free of water and ice. That region is then available to receive water from and supply water to, a fuel cell (102; 402) nominally upon start-up. The region having the relatively more-rapid fill rate (R2; R2′) may typically be of relatively lesser volume, and may be positioned either relatively below or relatively above the other region(s).

摘要： A method of processing a porous article includes distributing a blended material that includes an electrically conductive material and a binder into a cavity of a mold that is at a temperature below a curing temperature of the binder. The electrically conductive material is formed from particles of the electrically conductive material that have a size distribution such that 10 vol % of the particles are less than 12 micrometers in diameter, 50 vol % of the particles are less than 27 micrometers in diameter, and 90 vol % of the particles are less than 53 micrometers.

摘要： A decontamination procedure for a fuel cell power plant (10) includes operating the plant to produce electrical power for an operating period, and then terminating operation of the plant (10) for a decontamination period, and then, whenever optimal electrical production of a plant fuel cell (12) is reduced by at least 5% by contaminants adsorbed by fuel cell electrodes (24, 42), decontaminating the fuel cell (12) of the plant (10) during the decontamination period by oxidizing contaminants adsorbed by electrodes (24, 42) of the fuel cell. Oxidizing the contaminants may be accomplished by various steps including exposing the electrodes (24, 42) to flowing oxygen; to heated flowing oxygen; to a sequence of start-stop cycles; and, to varying controlled potentials.

摘要： Coolant velocity greater than zero everywhere within the coolant channels (78, 85) of fuel cells (38) in a fuel cell stack (37) is assured by providing a flow of gas in the coolant channels, the flow being created by gas pressure from a source (92) of pressurized gas, an oxidant reactant air pump (52), a source (75) of hydrogen-containing fuel, or the fuel outlet (47), or the outflow of a condenser (59). Positive pressure may be applied to the coolant inlet (66) or negative pressure from an eductor (97) may be applied to a gas outlet (90) of the coolant channels, or both. Using gas to induce flow within the coolant channels eliminates the need for a bubble-clearing liquid pump and reduces liquid inventory and other plumbing; this makes the fuel cell power plant more freeze tolerant. Biphase flow from the condenser, which may be a vehicle radiator (120), renders the coolant return flow more freeze tolerant. Separate cooler plates (122) may be used with a coolant management system (125).

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 coolant source, and a fluid permeable anode reactant flow field plate adjacent to said coolant source. The anode reactant flow field plates pass coolant from the coolant sources into the cells where the coolant is evaporated to cool the cells. The cathode flow field plates prevent reactant crossover between adjacent cells. By providing a single permeable plate for each cell in the power plant the amount of coolant present in the power plant at shut down is limited to a degree which does not require adjunct coolant purging components to remove coolant from the plates when the power plant is shut down during freezing ambient conditions. Thus the amount of residual frozen coolant 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 frozen coolant that must be melted during startup. Pressure in the coolant source is preferably greater than ambient pressure, and pressure in the anode reactant flow field is greater than the pressure in the coolant source so as to prevent the coolant from flooding the cells. The power plant is well suited for use in powering vehicles.
摘要翻译： PEM燃料电池发电厂包括燃料电池，每个燃料电池具有阴极反应物流场板，其基本上不透液体，冷却剂源和与所述冷却剂源相邻的流体可渗透阳极反应物流场板。阳极反应物流场板将冷却剂从冷却剂源传递到冷却剂被蒸发以冷却电池的电池中。阴极流场板防止相邻电池之间的反应物交叉。通过为发电厂中的每个电池提供单个可渗透板，停电时存在于发电厂中的冷却剂的量被限制在不需要辅助冷却剂吹扫部件以在发电厂关闭时从板上去除冷却剂的程度在冷冻环境条件下下降。因此，在这种冷冻条件下在关闭期间在板中形成的发电厂中剩余的冷冻冷冻剂的量将受到限制。因此，由于在启动期间必须熔化的冷冻冷冻剂的量减少，因此发电厂可以重新启动并迅速达到完全的工作功率水平。冷却剂源中的压力优选大于环境压力，并且阳极反应物流场中的压力大于冷却剂源中的压力，以便防止冷却剂淹没电池。发电厂非常适合用于为车辆供电。

摘要： Coolant velocity greater than zero everywhere within the coolant channels (78, 85) of fuel cells (38) in a fuel cell stack (37) is assured by providing a flow of biphase fluid in the coolant channels, the flow being created by the outflow of a condenser (59). Positive pressure is applied to the coolant inlet (66) of the coolant channels. Biphase flow from an oxidant exhaust condenser, which may be a vehicle radiator (120), renders the coolant return flow more freeze tolerant.
