Polymer microspheres with different morphology and structure have various physico-chemical properties and functions. The design
synthesis and characterization of the functional polymer microspheres is briefly introduced. This paper summarizes the research progress on design
synthesis
characterization and application of the functional polymer microspheres incorporated proton exchange membrane for fuel cell. The resultant composite proton exchange membranes exhibit high proton conductivity
good methanol barrier property due to their high uptake and good water retention under low humidity.
