This study comprises the production and characterization of multifunctional silica nanoparticles and their incorporation into Nafion for proton exchange membrane fuel cell (PEMFC) applications. A two‐step method was used to produce Azole‐SiO2/Nafion; First, epoxy functional SiO2 nanoparticles were functionalized with 5‐Amino‐Tetrazole (Tet‐SiO2), 3‐Amino‐1,2,4‐Triazole (ATri‐SiO2), and 1H‐1,2,4‐Triazole (Tri‐SiO2) via ring opening of the epoxy unit. After the synthesis of functional nanoparticles, Nafion composite membranes were prepared via the mechanical mixing method. Azole‐SiO2/Nafion composite membranes were characterized by FT‐IR, and TGA were used to investigate the structural thermal properties, and the results indicated that they were thermally stable up to approximately 380 °C. The anhydrous conductivity of the Nafion composite membranes were studied by a dielectric impedance analyzer and maximum conductivity was measured for N‐SiO2‐Tet10 as 1.01 × 10−2 (Scm−1) at 160 °C.

Proton-conducting materials have attracted considerable interest because of their extensive application in energy storage and conversion devices. Among them, metal–organic frameworks (MOFs) present tremendous development potential and possibilities for constructing novel advanced proton conductors due to their special advantages in crystallinity, designability, and porosity. In particular, several special design strategies for the structure of MOFs have opened new doors for the advancement of MOF proton conductors, such as charged network construction, ligand functionalization, metal-center manipulation, defective engineering, guest molecule incorporation, and pore-space manipulation. With the implementation of these strategies, proton-conducting MOFs have developed significantly and profoundly within the last decade. Therefore, in this review, we critically discuss and analyze the fundamental principles, design strategies, and implementation methods targeted at improving the proton conductivity of MOFs through representative examples. Besides, the structural features, the proton conduction mechanism and the behavior of MOFs are discussed thoroughly and meticulously. Future endeavors are also proposed to address the challenges of proton-conducting MOFs in practical research. We sincerely expect that this review will bring guidance and inspiration for the design of proton-conducting MOFs and further motivate the research enthusiasm for novel proton-conducting materials.
