Abstract Experimental evaluation using screening design is employed to determine the significant parameters in preparation of anion exchange membranes applicable in solid alkaline fuel cell. Anion exchange membranes are prepared based on quaternized polysulfone using trimethylamine and N,N,N′,N′‐tetramethyl‐1,6‐hexanediamine as amination agents. Plackett Burman and Fractional Factorial designs are used to model variable factors and responses. Chloromethylation time and temperature, amination time and temperature and molar ratio of amines to chloromethylated sites on the polymer chain are studied as the model variables. Moreover, ex situ ionic conductivity (at 25 and 60 °C) and swelling ratio (at 25 °C) of the prepared anion exchange membranes are considered as the responses. Finally, based on analysis of variance using statistical software, the chloromethylation time, the amination temperature and the molar ratio of amines are defined as the dominant parameters which significantly affect the performance of the anion exchange membranes.
