摘要： An inlet fuel distributor (10-10d) has a permeable baffle (39, 54,54a, 60) between a fuel supply pipe (11, 83) and a fuel inlet manifold (12, 53, 53a, 63) causing fuel to be uniformly distributed along the length of the fuel inlet manifold. A surface (53, 68) may cause impinging fuel to turn and flow substantially omnidirectionally improving its uniformity. Recycle fuel may be provided (25, 71) into the flow downstream of the fuel inlet distributor. During startup, fuel or inert gas within the inlet fuel distributor and the fuel inlet manifold may be vented through a valve (57, 86) in response to a controller (58, 79) so as to present a uniform fuel front to the inlets of the fuel flow fields (58).

摘要： In a fuel cell stack (l la), a larger number of fuel cells (18-21, 33-36) are interposed between successive cooler plates (13-15) without creating excessively high temperatures in those fuel cells (33-36) which. are remote from the cooler plates, by virtue of increased air flow in air flow field channels (30a) which are deeper in fuel cells (30-36) remote from the cooler plates, compared with the flow field channels (30, 30b) which are in fuel cells (18-21) adjacent to the cooler plates. The thickness of air flow field plates (29b) may be increased to accommodate the increased depth of the air flow channels (30a). Fuel cells (18a) adjacent the cooler plate may have air flow field channels (30b) which are more shallow than normal whereby increased air utilization therein will be balanced by decreased air utilization in the cells (33-36, 33a) having deeper air flow channels (30a); in this case, the channels (30a) may be normal or deeper than normal.
摘要翻译：在燃料电池堆（11a）中，较大数量的燃料电池（18-21,33-36）插入连续的冷却板（13-15）之间，而不会在那些燃料电池（33-36）中产生过高的温度，哪一个。与流场通道（30,30b）相比，由于在远离冷却器板的燃料电池（30-36）中更深的空气流场通道（30a）中的空气流量增加，远离冷却器板。在与冷却器板相邻的燃料电池（18-21）中。可以增加空气流场板（29b）的厚度以适应气流通道（30a）的增加的深度。靠近冷却器板的燃料电池（18a）可以具有比正常更浅的空气流场通道（30b），由此在其中增加的空气利用将通过具有较深气流的电池（33-36,33a）中的空气利用减少来平衡通道（30a）; 在这种情况下，通道（30a）可以是正常的或比正常的更深。

摘要： A PEM fuel cell assembly includes cooler plates (10) with internal coolant manifolds (25) isolated from the cell stack assembly by an isolation gap (28) to minimize the risk of contamination of the cells by antifreeze. The internal coolant manifolds are formed by seal assemblies (24), each disposed between inlet or outlet openings (14, 15) in projections (16) of each cooler plate extending outwardly from the fuel cell planform (20) to provide a gap (28), which may be used as an air turn manifold. Flanges (40) with through holes (41) may receive tie rods to assist assembly of a fuel cell stack with the cooler plate.

摘要： A plurality of cooler plates (9) are disposed between fuel cells (8) in a stack (7) and have protrusions (12, 13) which include coolant inlet and outlet channels (15). The protrusions are surrounded by an elastomeric sealant material (35, 36) which forms a seal with the manifold structures (27, 28) to form coolant inlet and outlet manifolds (17, 20). The sealant material prevents coolant from entering fuel cells along the edges thereof, thereby preventing the fuel cells from being poisoned by the coolant. The coolant inlet and outlet manifold structures (27, 28) also define reactant gas manifolds (18, 21).

摘要： A fuel cell power plant (19) has a stack of fuel cells (20) cooled by a mixture of water with a non-volatile, miscible fluid that sufficiently depresses the freezing point, such as polyethylene glycol (PEG). The water and fluid are mixed in a reservoir (21), a small pump (22, 60) flows the mixture through coolant channels (28) in or adjacent water transport plates (29); heat of the catalytic reaction warms the water transport plates causing water to evaporate therefrom thereby cooling the stack. The PEG is non-volatile at stack operating temperature and does not evaporate; concentrated PEG is returned (33) to the reservoir (21). Water in the process air flow channels (41), including evaporated process water, is recovered in a condensation-rate-controlled (53, 54)) condenser (46) in communication (48) with the reservoir (21) for remixture with the concentrated PEG solution. Hydrophobic gas diffusion layers (72) shield the proton exchange membrane (70) from the PEG.

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 maybe 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.
