Abstract: The present disclosure relates to systems and methods for reducing and/or preventing damage to metal plate stacks in fuel cell stacks. The present disclosure relates to methods of minimizing electrical shorting due to debris and/or burrs from laser cutting, sharp edges from laser cutting, and/or over-compression of a backfeed and/or a frontfeed ports.

Abstract: A fuel cell stack includes a fuel cell including a bipolar plate sheet. The bipolar plate sheet includes an outer sheet edge having a first longitudinal edge and a first transverse edge, a first surface, and a first load-bearing extension arranged on the first longitudinal edge or the first transverse edge. The first load-bearing extension is configured to engage with an alignment bar or a support bar of a fuel cell stack assembling apparatus within which the fuel cell stack is compressed for assembly such that, during compression of the fuel cell stack, the first load-bearing extension engages the alignment bar or the support bar so as to transfer force loads from the alignment bar or the support bar away from the first outer sheet edge and toward a central area of the first bipolar plate sheet.
