A liquid electrolyte fuel cell power plant (6) includes a stack (7) of fuel cells (8) demarcated by fluid impermeable separator plates (19, 23) with additional wicking to ensure backflow of condensated electrolyte from a condensation zone (27) back through the active area of the fuel cells. Wicking material (49) is disposed in channels interspersed with reactant gas channels (20, 21); wicking material (54) is disposed in zones (53) formed within electrode substrates (16, 17); wicking material (58) is disposed on the base surface of reactant gas channels (20, 21); wicking material (62) is disposed between the ribs (50) of the separator plates (19, 23) and the adjacent surfaces of the substrates (16, 17); and wicking material (65) is formed as ribs on planar separator plates (19a, 23a), the spaces between the wicking ribs (65) comprising the reactant gas channels (20, 21).
