A fuel cell bipolar plate including a fuel side having a series of fuel channels defining respective fuel paths and an oxidant side having a series of oxidant channels defining respective oxidant paths. At least some of the fuel channels are offset from adjacent oxidant channels in a direction transverse to the fuel and oxidant paths. A fuel manifold is connected to the fuel channels, while an oxidant manifold is connected to the oxidant channels. One of the two manifolds is located between the biplate and the other manifold, where a connector extends from whichever manifold is outermost to the associated fuel or oxidant channels.

[ We claim:] [1.]1. A fuel cell, comprising:at least two membrane electrode assemblies;a corrugated bipolar plate located between the membrane electrode assemblies defining a fuel side and an oxidant side and the fuel side includes an alternating series of ridges and channels and the oxidant side includes an alternating series of ridges and channels, each of the channels defining a respective inlet and a respective outlet;a fuel manifold operably connected to the channels on the fuel side and an oxidant manifold operably connected to the channels on the oxidant side, one of the fuel manifold and the oxidant manifold defining an outermost manifold and the other of the fuel manifold and the oxidant manifold defining an innermost manifold located between the outermost manifold and the bipolar plate; anda connector extending from the outermost manifold to the associated channels and separately connecting the outermost manifold to each of the associated channels.
