Abstract

The present invention herein provides a bipolar metal plate (702, 704). The bipolar metal plate includes a first side and a second side being adapted to have a first set of predefined channels and a second set of predefined channels, respectively. The first set of predefined channels is adapted to provide a first flow field for a first reactant. Similarly, the second set of predefined channels is adapted to provide a second flow field for a second reactant. One or more first channels of the first set of predefined channels terminating at a first inlet/outlet on the first side of bi-polar metal plate are adapted to have a first bypass flow field to maintain the one or more first channels active. Similarly, one or more second channels of the second set of predefined channels are adapted to have a second bypass flow field to maintain the one or more second channels active.
