Abstract
A fuel cell assembly includes first and second compression members. Two or more membrane electrode assembly (MEA) stacks are disposed between the compression members, each MEA stack having a positive and negative end. A first current collector is electrically coupled to a positive end of a first stack of the MEA stacks. A second current collector is electrically coupled to a negative end of a second stack of the MEA stacks. A current shunt is disposed between the compression members and electrically couples the MEA stacks.
