摘要： A bipolar plate assembly and fuel cell stack with reduced leakage and a method of assembling a bipolar plate and fuel cell stack. The bipolar plates include—in addition to reactant channels and coolant channels that are fluidly coupled to inlet and outlet flowpaths, integrally-formed seals to help reduce leakage by maintaining fluid isolation of the reactants and coolant as they flow through their respective channels and flowpaths. The size and shape of the seals promotes secure plate-to-plate contact, even during plate side-to-side misalignment that can occur when arranging the various plates into the stack.

摘要： A fuel cell flow field plate providing a uniform gas flow pressure includes a first metal plate and a second metal plate. The first metal plate defines a first opening for providing a first reactant gas to a fuel cell with a first metal bead that surrounds the first opening. The first metal bead is an embossment that defines a first channel. A first plurality of tunnels provides a passage into and out of the first metal bead. Each tunnel of the first plurality of tunnels has an inlet tunnel section that leads to the first metal bead and an outlet tunnel section that extends from the first metal bead to provide the first reactant gas to first reactant gas flow channels defined by the first metal plate. Characteristically, the inlet tunnel section and the outlet tunnel section each having a curved cross section with an opened base side.

摘要： A fuel cell flow field plate providing a uniform gas flow pressure includes a first metal plate and a second metal plate. The first metal plate defines a first opening for providing a first reactant gas to a fuel cell with a first metal bead that surrounds the first opening. The first metal bead is an embossment in the second metal plate that defines a first channel. The first metal plate also defines a first pressure distributing structure that decreases pressure variation is a seal formed with the first metal bead. A second metal plate aligns with the first metal plate.
