The advances development of proton exchange membrane with high proton conductivity and balanced stability in fuel cells

In the proton exchange membrane fuel cell, (PEM) serves as both main conductor of protons and fuel-blocking membrane. Thus, high conductivity excellent stability are expected for PEMs at same time. According to chemical structure, this review divides PEM into three groups. Recently, high-performance has been made possible by controlling organic–inorganic hybrid composite membranes, nanofiber membranes. One them, is distinguished long-range order capable achieving strong with exceptional stability. The accomplished presence an acid-rich layer, acid–base interaction, transport channel in also summarized paper. We believe that our discussion will help researcher create pave way further developments field energy materials a whole.
