(a) Stability of PA/PBI/PWA-meso-silica and PA/PBI membrane cells and (b) membrane conductivity as a function of test time, measured at 200°C and 200 mAcm−2. (c) Scheme showing the in situ formation of PA/phosphosilicate nanoclusters from the interaction between the meso-silica and PA during the fuel cell operation conditions [106, 107].
