Construction of three-dimensional proton-conduction networks with functionalized PU@PAN/UiO-66 nanofibers for proton exchange membranes.

Proton exchange membranes (PEMs) play an important role in fuel cells. For realizing a nanofiber (NF) structure design in PEMs, the material should have tunable pores and a high specific area. In this study, we attempt to design a novel NF with synergistic architecture doped MOF for constructing three-dimensional (3D) proton conduction networks in PEMs.
