Branched fluid channel for improving fluid flow through a fuel cell

摘要

A flow field geometry formed in a separator plate of a fuel cell includes a plurality of straight inlet legs including a first lateral inlet leg laterally offset from a first inlet leg and a dividing junction associated with each of the plurality of straight inlet legs. The dividing junction divides a straight inlet leg into a plurality of branched legs. A number of a first set of branched legs associated with the first lateral inlet leg is greater than a number of a set of branched legs associated with the first inlet leg.
