Abstract
A fuel cell assembly provides for the delivery of fluid into a channel of a fluid flow field plate in alternating flow directions through the channel for delivery of the fluid to a membrane-electrode assembly. The fuel cell includes a fluid flow field plate having a channel for delivery of fluid to a membrane-electrode assembly, the channel having a first inlet/outlet port communicating therewith and a second inlet/outlet port communicating therewith; and a fluid delivery system connected to the fluid flow field plate adapted for bi-directional delivery of fluid into the channel of the fluid flow field plate.
