Abstract: A fuel cell stack includes a fuel cell including a bipolar plate sheet. The bipolar plate sheet includes an outer sheet edge having a first longitudinal edge and a first transverse edge, a first surface, and a first load-bearing extension arranged on the first longitudinal edge or the first transverse edge. The first load-bearing extension is configured to engage with an alignment bar or a support bar of a fuel cell stack assembling apparatus within which the fuel cell stack is compressed for assembly such that, during compression of the fuel cell stack, the first load-bearing extension engages the alignment bar or the support bar so as to transfer force loads from the alignment bar or the support bar away from the first outer sheet edge and toward a central area of the first bipolar plate sheet.

Abstract: The present disclosure relates to systems and methods for reducing and/or preventing damage to metal plate stacks in fuel cell stacks. The present disclosure relates to methods of minimizing electrical shorting due to debris and/or burrs from laser cutting, sharp edges from laser cutting, and/or over-compression of a backfeed and/or a frontfeed ports.

Abstract: The present disclosure generally relates to systems and methods for inducing a secondary flow from a first groove in a bipolar plate of a fuel cell to a second groove in the bipolar plate over a first land in the bipolar plate wherein the land is adjacent to a compressed section of a gas diffusion layer in the fuel cell, and wherein the secondary flow increases locally available oxygen and hydrogen at the membrane electrode assembly adjacent to the compressed section of the gas diffusion layer.

Abstract: An electrochemical cell has a membrane located between two flow field plates. On a first side of the membrane, there is a porous support surrounded by a seal between the membrane and the flow field plate. There is a gap between the porous support and the seal at the surface of the membrane. On a second side of the membrane, there is a seal between the membrane and the flow field plate located inside of the gap in plan view. The electrochemical cell is useful, for example, in high pressure or differential pressure electrolysis in which the second side of the membrane will be consistently exposed to a higher pressure than the first side of the membrane.

Abstract: An electrochemical cell has first and second flow fields on opposite sides of a membrane. The first flow field has a set of generally linear channels in which the flow of a fluid in the field is contained between parallel elongate ridges. The second flow field is defined by a set of parallel discontinuous ridges. Preferably most ridge segments in the second flow field are oblique, for example perpendicular, to and overlap with two or more ridges of the first flow field. The flow fields may be used in, for example, water electrolysis cells including high or differential pressure polymer electrolyte membrane (PEM) electrolysis cells.

Abstract: A fuel cell assembly includes a first bipolar plate, a second bipolar plate, and a diffusion-electrode assembly. A first top surface of the first plate includes a first seal protruding upwardly and a first raised feed channel adjacent the first seal and protruding upwardly. A second bottom surface of the second plate includes a second seal protruding downwardly and a second raised feed channel adjacent the second seal and protruding downwardly. The diffusion-electrode assembly includes a membrane layer having a membrane frame extending therefrom and two gas diffusion layers. The first and second plates are arranged parallel, the first and second seals align with each other, and the first and second raised feed channels align with each other. The first and second raised feed channels contact the membrane frame arranged therebetween so as to prevent mechanical deformations of the first and second plates.
