Abstract
A fuel cell assembly includes a pair of corrugated bipolar plates. Each of the plates is defined by peak portions and sidewalls connecting the peak portions. The plates are fitted and nested within each other such that the sidewalls are in direct contact. Some of the sidewalls include a stepped shoulder portion such that each of the some of the sidewalls and the peak portions adjacent thereto form a stair-step profile and define a flow channel having a depth greater than a width.
