NOVELTY - A fuel cell assembly (220) comprises first flow field plate (240); second flow field plate (242); membrane electrode assembly (MEA) (225); and gaskets (234, 236) between first and second flow field plates. The gasket comprises first surface having first human perceivable feature associated with anode catalytic layer and second surface having second human perceivable feature associated with cathode catalytic layer. The first perceivable feature is discernable from second perceivable feature, and portion of gasket extends beyond periphery of first and second flow field plates.    USE - As a fuel cell assembly (claimed), useful in automobiles.    ADVANTAGE - The use of perimeter gaskets eliminates MEA orientation errors during fuel cell assembly, thus saving cost, time, and yields.    DETAILED DESCRIPTION - A fuel cell assembly (220) comprises a first flow field plate (240); second flow field plate (242); membrane electrode assembly (MEA) (225) provided between the first and second flow field plates, where MEA comprises first and second gas diffusion layers (GDLs) (224, 226) and a membrane (222) provided between an anode catalytic layer (230) and a cathode catalytic layer (232); and gaskets (234, 236) provided between the first and second flow field plates and relative to a periphery of the MEA. The gasket comprises first surface having a first human perceivable feature associated with the anode catalytic layer and a second surface having a second human perceivable feature associated with the cathode catalytic layer. The first perceivable feature is discernable from the second perceivable feature, and at least a portion of the gasket comprising the first and second human perceivable features extends beyond periphery of the first and second flow field plates. The first and second human perceivable features respectively comprise a first color and a second color discernable from the first color. An INDEPENDENT CLAIM is included for a method of assembling a stack of fuel cell components.    DESCRIPTION OF DRAWING(S) - The figure shows exploded diagram of the fuel cell.
