Claim:
1. A method of assembling a fuel cell stack, the method comprising: arranging a plurality of substantially planar fuel cells along a stacking dimension within a stacking fixture, each of the plurality of substantially planar fuel cells comprising at least a membrane electrode assembly placed facingly-adjacent to a bipolar plate that defines at least one integrally-formed edge extension therein; pouring a potting material into a portion of the stacking fixture that defines a shape that substantially corresponds to the integrally-formed edge extension such that upon curing, the potting material forms a datum that is secured to the arranged fuel cells along the stacking dimension to provide an increased resistance to inter-cell movement of the plurality of substantially planar fuel cells along a dimension that is substantially orthogonal to the stacking dimension; and securing the plurality of substantially planar fuel cells within a housing.
