“…In light of these considerations, the present work shows how the properties of a thin short-side-chain Aquivion ® membrane with a thickness of 50 µm, containing Ce-radical scavenger powder (C98-05S-RSP), assessed in a differential pressure PEM electrolyser, can considerably affect the performance and stability with respect to bare Aquivion ® membranes, extruded and reinforced (E98 05S and R98 05S, respectively), as previously investigated [18,44].…”

“…Among all electrolysis technologies, PEM electrolysers can work at a much higher current density, e.g., 4 A cm −2 and at cutting-edge efficiency, thus saving capital costs and energy consumption [12][13][14][15][16][17][18]. Moreover, PEM electrolysis can operate in high-pressure conditions in order to reduce the downstream mechanical gas compression when renewable H 2 needs to be stored, leading to higher efficiency, lower costs and increased safety levels [19,20].…”

A Ce-radical scavenger-based perfluorosulfonic acid (PFSA) Aquivion® membrane (C98 05S-RSP) was developed and assessed for polymer electrolyte membrane (PEM) electrolyser applications. The membrane, produced by Solvay Specialty Polymers, had an equivalent weight (EW) of 980 g/eq and a thickness of 50 μm to reduce ohmic losses at a high current density. The electrochemical properties and gas crossover through the membrane were evaluated upon the formation of a membrane-electrode assembly (MEA) in a range of temperatures between 30 and 90 °C and at various differential pressures (ambient, 10 and 20 bars). Bare extruded (E98 05S) and reinforced (R98 05S) PFSA Aquivion® membranes with similar EWs and thicknesses were assessed for comparison in terms of their performance, stability and hydrogen crossover under the same operating conditions. The method used for the membrane manufacturing significantly influenced the interfacial properties, with the electrodes affecting the polarisation resistance and H2 permeation in the oxygen stream, as well as the degradation rate, as observed in the durability studies.

“…28 In addition, introducing a second polymer is also an effective way to prepare high-performance proton membranes. Siracusano et al 29 investigated perfluoro sulfonic acid (PFSA) aquivion s short side chain reinforced membranes with an equivalent weight of 980 g eq. À1 and a thickness of 50 mm produced by Solvay Specialty Polymers, and introduced expanded PTFE fibers to reinforce aquivion s membranes.…”

“…Although the reduction of membrane thickness in PEMWE is an important route to achieve proper efficiency at high-current density, thinner membranes can bring the risk of an increase of gas crossover and therefore compromise the mechanical stability of the MEA. Recently, Siracusano et al [71] demonstrated a reinforced short-sidechain PTFE-based membrane that enables stable electrolysis operation at 4 A cm −2 . Still, at the present stage, novel materials to replace PFSA membranes need to undergo durability studies for the evaluation of their long-term performance.…”

During the past decades, a significant amount of excellent scientific results has been generated in the field of polymer electrolyte membrane water electrolysis (PEMWE). Compared to current state-of-the-art technologies, PEMWE offers the opportunity to produce green hydrogen with zero carbon emissions. However, the membrane electrode assembly (MEA), whose price is still high for a rather limited lifetime, needs further improvement in terms of performance, cost, and durability. In order to efficiently process novel materials, accelerated stress tests (ASTs) can be implemented to provoke and investigate cell ageing processes and assess failure modes under real-life conditions. In this review, the different accelerated stressors of the main components of the MEA are discussed, and recent publications of ASTs in the study of PEMWE cell durability are summarized. Furthermore, a concise review of the degradation mechanisms for the individual MEA components depicted in recent publications is presented. The different aspects identified in this review serve as a roadmap to further advance the durability of novel stack materials.
