A groove is placed in the repeating parts of a fuel cell stack assembly, such parts being, for example, the indvidual fuel cell backing layers and the separator plates. The groove assists in sealing manifolds to the fuel cell stack assembly, overcoming the "skyline" problem that frequently occurs when multiple repeating parts are assembled together.
