摘要： An electro-conductive plate assembly for a fuel cell has a pair of stamped plates joined together to define a coolant volume therein. Each of the pair of stamped plates has a flow field on a major outer surface arranged to maximize the contact area between major inner surfaces of the plates while allowing coolant to distribute and flow readily within the coolant volume. The flow fields formed on the major outer surfaces provide corresponding sets of lands on the major inner surfaces that contact to form a third flow field of the coolant volume. The third flow field formed by the lands includes a plurality of longitudinal channels and an array of flow disruptors. The bipolar plate assembly further includes a seal arrangement and integral manifolds to direct reactant gas and coolant flow through the fuel cell.

摘要： A PEM fuel cell having serpentine flow field channels wherein each channel has an inlet leg, an exit leg, at least one medial leg therebetween and hairpin curves connecting the legs to each other. The legs all extend in the same general direction between a gas supply and gas exhaust manifold. One of the inlet and exit legs is longer than the other while the medial leg is shorter than the shortest of the inlet/exit leg. The land(s) defining the medial leg(s) of adjacent channels are generally aligned lengthwise.
摘要翻译：具有蛇形流场通道的PEM燃料电池，其中每个通道具有入口腿，出口腿，其间的至少一个中间腿以及将腿彼此连接的发夹曲线。两条腿都在气体供应和排气歧管之间沿相同的大致方向延伸。入口和出口腿中的一个比另一个长，而内侧腿短于入口/出口腿的最短。限定相邻通道的内侧腿的陆地一般沿纵向排列。
