A fuel cell includes a membrane electrode assembly (46) having a first
reactant flow field (80) secured adjacent a first or second surface (48,
50) of the assembly (46) for directing flow of a first reactant adjacent
the first or second surface of the assembly (46). The first reactant flow
field (80) defines a plurality of two-pass circuits (82, 84, 86, 88), and
each two-pass circuit (82) is in fluid communication with both a first
reactant inlet (90) for directing the first reactant into the fuel cell
(12), and with a first reactant outlet (92) for directing the first
reactant out of the fuel cell (12). The plurality of two-pass circuits
(82) facilitate water movement (112) toward the reactant inlet (90) to
aid in passive maintenance of fuel cell (12) water balance.
