    摘要: A fluid flow plate for an electrochemical assembly has a plurality of first fluid flow channels extending across an active area of the flow plate to define a first fluid flow field of the fluid flow plate and a plurality of second fluid flow channels extending across the active area of the flow plate to define a second fluid flow field of the fluid flow plate. An array of first fluid transfer points is disposed along an edge of the first fluid flow field for communicating fluid into or out of the first fluid flow channels. An array of second fluid transfer points is disposed along an edge of the second fluid flow field for communicating fluid into or out of the second fluid flow channels. A first fluid gallery a first peripheral edge portion bounded by the array of first fluid transfer points and has a second peripheral edge portion forming a first fluid communication edge of the fluid flow plate. A second fluid gallery has a first peripheral edge portion bounded by the array of second fluid transfer points and has a second peripheral edge portion forming a second fluid communication edge of the fluid flow plate. The first fluid gallery and the second fluid gallery are shaped such that the combined lengths of the second peripheral edge portions are longer than the first peripheral edge portion of the second fluid gallery or the first fluid gallery. Increasing the lengths of the second peripheral edge portions of each gallery to the maximum possible length compared to the length of fluid transfer points (i.e. width of the active flow field area) optimizes fluid distribution into the channels of the flow plate.

    摘要: A fuel cell stack assembly comprises fuel cells disposed in a stacked configuration, each cell substantially parallel to an x-y plane and including a tab extending laterally from an edge of a plate in the cell in the x-direction to form an array of tabs extending along a side face of the fuel cell stack in a z-direction orthogonal to the x-y plane. A connector engages with the tabs of the fuel cell stack. The connector comprises a support region and engagement regions, each engagement region bounded by the support region and configured to receive one of the array of tabs by engagement in the x-direction. The connector has flexible conductors, each of the flexible conductors laterally extending from the support region over at least a portion of one of the engagement regions and configured to be deflected away from the support region by a received tab.

    摘要: A bipolar fluid flow plate for an electrochemical assembly comprises a plurality of first fluid flow channels extending across a face of the flow plate to define a first fluid flow field of the fluid flow plate and a plurality of second fluid flow channels extending across a face of the flow plate to define a second fluid flow field of the fluid flow plate. The pluralities of first fluid flow channels and second fluid flow channels both occupying a common channel plane. An array of first fluid transfer points is disposed along an edge of the first fluid flow field for communicating fluid into or out of the first fluid flow channels. An array of second fluid transfer points is disposed along an edge of the second fluid flow field for communicating fluid into or out of the second fluid flow channels. A first fluid gallery has a first peripheral edge portion bounded by the array of first fluid transfer points and has a second peripheral edge portion forming a first fluid communication edge of the fluid flow plate. A second fluid gallery has a first peripheral edge portion bounded by the array of second fluid transfer points and has a second peripheral edge portion forming a second fluid communication edge of the fluid flow plate. The first fluid gallery occupies a first gallery plane and the second fluid gallery occupies a second gallery plane different from the first gallery plane. Both the first gallery plane and the second gallery plane are disposed within the channel plane. This structure enables the feeding of multiple different fluids into coplanar channels across the full width of a flow field.
