Abstract
A fuel cell stack (60) comprises a plurality of manifolds (50) separated by membranes (37). Each manifold (50) forms overlapping chambers (34, 36) for adjacent cells (32) such that the depth of chambers for adjacent cells is not additive. In the preferred embodiment, the manifolds (50) are formed of a plastic material with conductive vias formed therethrough to reduce the cost associated with graphite vias.
