The system (10) controls at least one of a pressure of the reactant streams (16A, 16B) within at least one of an anode flow field (28) and a cathode flow field (36), a flow rate of the reactant streams (16A, 16B) flowing through the anode and/or cathode flow fields (26, 28), a temperature of a coolant fluid passing through a sealed coolant flow field (44), and a flow rate of the coolant fluid; so that water (14) moves from a water reservoir (18A, 18B) into the reactant stream (16A, 16B) whenever power generated by the fuel cell (20) is between about 80% and about 100% of a maximum fuel cell power output, and so that water (14) moves from the reactant stream (16A, 16B) into the water reservoir (18A, 18B) whenever fuel cell power is less than about 75% of the maximum power output. |
