Abstract
A fuel cell stack includes a plurality of fuel cells arranged in a stack configuration extending along a z-axis, wherein each fuel cell includes a membrane electrode assembly interposed between a pair of bipolar plates, and each membrane electrode assembly has a total active area measured in an x-y plane that is generally perpendicular to the z-axis. Each bipolar plate includes a plurality of common passages extending generally parallel to the z-axis. The total active area of each membrane electrode assembly includes a plurality of base active areas arranged co-planar in the x-y plane along an x-axis.
