This report presents the results belonging to the developed recast membranes containing recombination catalysts (RC) to limit the effect of the H2 crossover at the oxygen site of AEMWE. A first set of membranes was prepared using the commercial polymer FAA-3, to optimize the preparation methodology and to determine the optimal RC content to be introduced. Subsequently, membranes were prepared using the APACHE polymer developed within the project. The membranes were characterized by Ion Exchange Capacity (IEC), Water and KOH Uptake, Scanning Electron Microscopy (SEM), creep tests, hydroxide conductivity in the in-plane configuration and ex-situ Hydrogen crossover. The values obtained are compared with those of the commercial FUMATECH (FAA3-50) and PiperION-40 membranes.

Abstract
This report presents the results belonging to the developed recast membranes containing recombination catalysts (RC) to limit the effect of the H2 crossover at the oxygen site of AEMWE. A first set of membranes was prepared using the commercial polymer FAA-3, to optimize the preparation methodology and to determine the optimal RC content to be introduced. Subsequently, membranes were prepared using the APACHE polymer developed within the project. The membranes were characterized by Ion Exchange Capacity (IEC), Water and KOH Uptake, Scanning Electron Microscopy (SEM), creep tests, hydroxide conductivity in the in-plane configuration and ex-situ Hydrogen crossover. The values obtained are compared with those of the commercial FUMATECH (FAA3-50) and PiperION-40 membranes.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
