摘要： A barrier film for a fuel cell is provided, including a polymeric membrane having a plurality of support features. The support features are adapted to militate against a deflection of the membrane under a pressure differential across the membrane. A fuel cell employing the barrier film has a first plate with a port formed therein, and a second plate disposed adjacent the first plate. The barrier film is disposed between the first plate and the second plate. The support features of the barrier film militate against an intrusion of the membrane into the port. A fuel cell stack formed from a plurality of the fuel cells is also provided.

摘要： A method of manufacturing a fuel cell membrane electrode assembly comprising forming and compressing a stack having a plurality of layers in a desired orientation. The layers comprise a membrane, a cathode, an anode, and at least one edge protection layer. The method includes providing at least one mechanical reinforcing layer adjacent the anode or cathode layer, and allowing the electrodes to relax under high heat to remove stress prior to lamination.

摘要： A bipolar plate for a PEM fuel cell is disclosed. The plate includes a plurality of channels, wherein the ends of the channels are staggered. The plate also includes a plurality of tunnels, wherein the ends of the tunnels are staggered. The plate further includes a cathode and an anode, wherein a portion of the cathode overhangs a portion of the anode. These staggered/offset features allow for an increase the capillary meniscus of water droplets passing therethrough, allowing for a reduction in the pressure required to move the water through the cell and out to the header volume of the stack.

摘要： A PEM fuel cell includes a first plate having a flow field for directing a first fluid along a surface thereof. A second plate includes a flow field for directing a second fluid along a surface thereof. A seal is disposed between the first plate and the second plate. The seal includes a plate margin defining a header aperture for delivering the first fluid to the first plate. The seal defines a carrier having a first side supported by the flow field of the first plate whereby the first fluid is permitted to flow directly from the first header aperture to the flow field of the first plate. The carrier includes a gasket arranged on a second side. The gasket precludes the first fluid from flowing directly from the header aperture to the flow field of the second plate.
