Abstract
The invention provides fuel cells and fuel cell stacks having a plurality of manifolds for providing reactive gases to cell layers. The manifolds are distributed across the planar area of the cells whereby the flow path lengths are reduced to the point that current collectors are not required. Substantial stack volume, cost and contact resistance reductions are also realized.
