Alessandra Carbone, researcher at CNR-ITAE, presented ANIONE results during the EUROMAT congress which took place in Frankfurt am Main, Germany, between 3 – 7 September 2023.
During the presentation “AQUIVION-BASED ANION EXCHANGE MEMBRANES: SYNTHESIS OPTIMIZATION VIA DISPERSANT AGENTS AND REACTION TIME”, Alessandra presented results on a simple two-step functionalization reaction to introduce quaternary ammonium groups onto Aquivion® perfuorinated backbone using a low toxici dispersant. It was demonstrated a very limited degradation of functional groups after immersion in alkaline solution, with only 2% of ion exchange capacity (IEC) reduction against 14% of the FAA3-50 commercial membrane. An electrolysis current density of 0.9 A cm-2 at 2.2 V and 90 °C, is achieved showing very promising applications for green hydrogen production A voltage efficiency (Veff) of about 80 % was recorded at 0.5 A cm-2, a typical operating current density in alkaline electrolysis.
