Abstract
A fuel cell includes a plurality of unit cells disposed in a stack. Each unit cell includes a membrane electrode assembly (MEA) having an anode and a cathode and a bipolar plate having a cathode side defining a recessed pocket in fluid communication with an air port, an anode side, and coolant channels between the cathode and anode sides. The bipolar plate is disposed against the MEA such that the cathode is disposed over the pocket. A flow guide is disposed in the pocket with a front side facing the MEA and a back side facing a bottom of the pocket. The flow guide has a plurality of embossments.
