Toward improved mechanical strength, oxidative stability and proton conductivity of an aligned quadratic hybrid (SPEEK/FPAPB/Fe₃O₄-FGO) membrane for application in high temperature and low humidity fuel cells

Fe₃O₄ anchored functionalized GO is applied as a magnetically active filler as well as a solid proton conductor to realize an aligned hybrid membrane electrolyte architecture with blended polymer matrix consisting of FPAPB and SPEEK.
