    摘要： A membrane-electrode assembly for use in a reversible fuel cell comprises an ion conductive membrane having first and second surface; a first electrocatalyst layer in contact with the first surface of the membrane said first electrocatalyst layer comprising at least one discrete electrolysis-active area (ELE1 i ) and at least one discrete energy generation-active area (EG1 i ). A second electrocatalyst layer is placed in contact with the second surface of the membrane said second electrocatalyst layer comprising at least one discrete electrolysis-active area (ELE2 i ) and at least one discrete energy generation-active area (EG2 i ). Each of the discrete electrolysis-active area(s) (ELE1 i ) on the first electrocatalyst layer correspond and are aligned with each of the discrete electrolysis-active area(s) (ELE2 i ) on the second electrocatalyst layer and each of the discrete energy generation-active area(s) (EG1 i ) on the first electrocatalyst layer correspond and are aligned with each of the discrete energy generation-active area(s) (EG2 i ) on the second electrocatalyst layer.

    摘要： Fuel cells (38) have passageways (83, 84) that provide water through one or both reactant gas flow field plates (75, 81) of each fuel cell, whereby the fuel cell is cooled evaporatively. The water passageways may be vented by a porous plug (not shown), or by a microvacuum pump (89). A condenser (59) may have a reservoir (64); the condenser (59) may be a vehicle radiator. A highly water permeable wicking layer (90) is disposed adjacent to one or both water passageways (83, 84) which exist between individual fuel cells (38). The passageways may be flow-through passageways (83) (FIG. 5) or they may be interdigitated passageways (83a, 83b) (FIG. 6) in order to increase the flow of water-purging air through the wicking layer (90) utilized to clear the stack of water during shutdown in cold environments. The inlet interdigitated channels (83c, 83d) may be only partially blocked at their outlet ends such as by a protrusion (104) or a hole (106) in order to ensure that any gas entering the inlet coolant passageways (83c, 83d) will not accumulate at the outlet end (101) of the inlet coolant passageways.

    摘要： A fuel cell stack (11) includes a plurality of contiguous fuel cells (13), each including a unitized electrode assembly (15) sandwiched between porous, anode (22) and cathode water transport plates (18). In areas where silicone rubber (29) or other elastomer covers edges of the fuel cells in order to form seals with an external manifold (27), adjacent edges of the water transport plates are supplanted by, or augmented with, an elastomer-impervious material (34). This prevents infusion of elastomer to the WTPs which can cause sufficient hydrophobicity as to reduce or eliminate water bubble pressure required to isolate the reactant gases from the coolant water, thereby preventing gaseous inhibition of the coolant pump. A preformed insert (34) may be cast into the water transport plates as molded, or a fusible or curable non-elastomer, elastomer-impervious in fluent form may be deposited into the pores of already formed water transport plates, and then fused or cured.
