“…Sivasankaran et al 24 fabricated the sulfonated silica incorporated polymeric membrane with a high PC of 0.32 S cm −1 , 60.5% more than commercial Nafion 117. The presence of SO 3 H group in SSiO 2 forms water‐conducting channels (ionic clusters), promoting proton transport by absorbing water molecules within the membrane surface 25,26 . Nanofillers will acts as a crosslinker between the matrix and water molecules, allowing easier transport of cations (H + ) through the membrane.…”

“…The octahedral (Ce‐O 4 ) arrangement was the favorable migration path for hopping and rotation process in perovskite material. The B3 membrane manifests higher conductivity (14.98 × 10 −3 Scm −1 at 80°C) than others at all temperatures due to the increased ionic clusters channels that furnished smooth convenience of protons 41 …”

“…The power density and current density of SPEEK/PAI/BaCeO 3 (06 wt%) were 267 mA cm −2 and 66 mW cm − 2 , respectively (Figure 10A). 41,43,44 The interfacial interplay of PAI and BaCeO 3 with SPEEK forming the hydrogen bond via polar groups and hinder the attack of free radicals in the HSO 3 groups. These restrictions made the minimal formation of radical in cathode sites and the benefit of BaCeO 3 nanoparticles favors the reduction reaction process 16,40,45 .…”
