Abstract

Anionic electrolyzers are expected to play a major role in the future massive production of green hydrogen. In this context, anionic membranes are still a bottleneck for their low conductivity and insufficient long-term chemical stability. In this paper we discussed and demonstrated the use of chemically modified, Aquivion®-based anionic membranes for water electrolysis. The membranes were subjected to different ageing treatments up to 3 M at 80 °C and showed better performance and durability than commercial Aemion™. Current density values around 130 mA cm−2 at 2 V were obtained with nickel foam as a benchmark electrode material.
