In this study for the first time, BaZrO3 nanoparticles as mixed metal oxides, with provision of strong acid sites and good hydrophilic nature were used for the preparation of organic–inorganic proton exchange membranes. Poly(vinyl alcohol)–BaZrO3 (PB) and poly(vinyl alcohol)/poly(vinyl pyrrolidone)–BaZrO3 (PPB) nanocomposite membranes have been prepared. PPB nanocomposite membranes containing 1 wt.% of BaZrO3 nanoparticles demonstrated high proton conductivity (6.01 × 10− 2 S/cm) at 70 °C. The highest peak power density of 28.98 mW/cm2 at Ep,max of 0.14 V with a peak current density (ip,max) of 201 mA/cm2 was achieved for the PEMFC which included PPB nanocomposite membranes at 70 °C.
