Poly(styrene-4-sulfonate)-grafted poly(vinylidene fluoride) (PVDF-g-PSSA) membranes were synthesised by free radical graft polymerization of polystyrene into PVDF films (50/xm) followed by sulfonation. Physical and electrochemical properties of the membranes were investigated. The membranes were tested as electrolytes in single cell-configuration system. The influence of working condition, as gas humidity and cell temperature on fuel cell performance was measured.
