SAFCs are recently being highlighted to overcome the disadvantages of AFCs. According to the recent works, alkaline doped PBI membranes exhibited good ionic conductivity, acceptable mechanical strength and high thermal stability. Suitable ionomer binder solutions for SAFCs were necessary. In this study, QPBIs having quaternized intermediate MGMC in the side group were synthesized for use as anion conducting ionomer binder. In addition, crosslinker was added in the catalyst slurry to improve the mechanical strength and chemical stability. The QPBIs were investigated in terms of FT-IR, NMR, ionic conductivity, KOH uptake etc. Moreover, MEAs prepared with different amounts of ionomer binder in electrodes were evaluated by CV and IV curve.
