“…To optimize the significance of the homogeneity evaluation and expedite experimental inquiries, the range of grid resolutions can be adjusted to match the characteristic length scales of a particular NW electrode application. This flexibility further enhances the value of the proposed strategy, making it suitable for a wide range of applications such as battery electrodes, 59,60 conductive/piezoelectric membranes, [61][62][63] air filters with active sterilization, 37 and fuel cells. 64 In all these applications, the conduction process of a network of onedimensional components, such as nanowires, nanotubes, and nanofibers, ultimately determines the overall system response.…”

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

“…Proton exchange membrane fuel cells (PEMFC) have the advantages of high conversion efficiency and low pollution emissions, and these characteristics have made it a technology of key interest. [4][5][6] The proton exchange membrane (PEM) is the heart of the PEMFC, facilitating the transfer of protons from the anode to the cathode to complete the circuit cycle and acting as a separator between the oxidizer and the fuel. [7][8][9][10] Most PEMs nowadays consist of perfluoro sulphonic acid membranes such as Nafion.…”

In this paper, sulfonic acid functionalized benzothiazole ionic liquid ([(CH2)3SO3HBth] [H2PO4]) and graphene oxide were combined together through the cation‐π. The sulfonated poly (ether ether ketone) was doped with ionic liquid‐modified GO (IL‐GO) to prepare the SPEEK/IL‐GO composite membrane through the solution casting method. The SO3H and benzothiazole rings act as both proton acceptors and proton donors during proton transport and can replace the role of water in medium‐ and high‐temperature environments, increasing the proton transport sites to a certain extent and increasing the proton conductivity of the SPEEK/IL‐GO composite membrane. The proton conductivity of the SPEEK/IL‐GO‐2 composite membrane achieved an 18.02 mS/cm at 120°C, which is 2.43 times higher than that of the pristine SPEEK membrane. This paper provided a method for increasing proton conductivity and limiting IL loss of the SPEEK membrane.Highlights [(CH2)3SO3HBth][H2PO4] and graphene oxide were combined through cation‐π. The benzothiazole ring and SO3H form acid–base pairs. The proton conductivity of SPEEK/IL‐GO‐2 membrane achieved 18.02 mS/cm.
