Influence of incorporated nanoparticles on the ionic conductivity of MF-4SC membrane

Prospects of practical application of hybrid membranes

“…Oxonium ions Protons matrix 3 SO group − pore walls was proposed [26,27]. According to this model, the introduction of nanoparticles into the pores of membranes leads to an expansion thereof and a simultaneous expansion of the poreconnecting channels, which limit the membrane conductivity [27].…”

Structure of perfluorinated membranes investigated by method of standard contact porosimetry

“…The introduction of electron conducting polymers not only expands the application areas for these membranes but also increases their selectivity and thermal stability [47,[126][127][128] that especially is important for fuel cell operating at high temperature. The perfluorinated membranes can be modified both with polyaniline and metal nanoparticles [129][130][131][132][133]. The polyaniline synthesized in a membrane can also be used as the reducing agent for recovery of metal nanoparticles which are catalysts of hydrogen splitting to protons and its recombination with oxygen on a membrane surface [134].…”

Perfluorinated Proton-Conducting Membrane Composites with Functionalized Nanodiamonds

“…However, for these composites based on perfluorinated sulfonic acid copolymers (Nafion, Aquivion) and NDs, a significant increase in proton conductivity was observed at a low humidity [32]. To interpret the effect, the authors of [32] used the hypothesis of limited elasticity of water-conducting pores of membranes, which was first proposed in [33]; the effect of diamond additives on conductivity was attributed to a change in the size of the pores and channels of the membrane material.…”
