<p>Recently, alkaline membrane water electrolysis, in which membranes are in direct contact with water or alkaline solutions, has gained attention. This necessitates new approaches to membrane characterization. We show how the mechanical properties of FAA3, PiperION, Nafion 212 and reinforced FAA3-PK-75 and PiperION PI-15 change when stress–strain curves are measured in temperature-controlled water. Since membranes show dimensional changes when the temperature changes and, therefore, may experience stresses in the application, we investigated seven different membrane types to determine if they follow the expected spring-like behavior or show hysteresis. By using a very simple setup which can be implemented in most laboratories, we measured the “true hydroxide conductivity” of membranes in temperature-controlled water and found that PI-15 and mTPN had higher conductivity at 60 °C than Nafion 212. The same setup was used to monitor the alkaline stability of membranes, and it was found that stability decreased in the order mTPN > PiperION > FAA3. XPS analysis showed that FAA3 was degraded by the attack of hydroxide ions on the benzylic position. Water permeability was analyzed, and mTPN had approximately two times higher permeability than PiperION and 50% higher permeability than FAA3. </p>

<p>This deliverable report summarizes recipes and protocols that were used to prepare MEAs for AEM electrolysis within the NEWELY project. The target of NEWELY is a low-cost, high performance, non-PGM electrolyser based on AEM technology operating with pure water or highly diluted KOH solution.</p>
<p>We have reached the NEWELY milestone (cell voltage below 2 V at 1 A/cm<sup>2</sup>) with catalyst coated substrate (CCS) MEAs. The produced MEAs were composed by OXYGN-N and H2GEN-M catalysts at the anode and cathode side respectively, supplied by CENmat. The ionomer was prepared with Poly(styrene-ethylenebutylene-styrene) (PSEBS) functionalized with 1,4-Diazabicyclo[2.2.2]octane (DABCO). The membrane was supplied as a thin film of 60 µm and the ionomer was the polymer dissolved either in Toluene (at CEA) or in Chloroform (at DLR Oldenburg) supplied by the Institute of Macromolecular Chemistry (IMC). Polybenzimidazole nanofibers mat covalently cross-linked with trimethylamine group was used as a second class of membrane and was tested in CCS-like MEA. These membranes were supplied by KIST.</p>
<p>The catalyst loading of the electrode were 4 mg/cm² and the catalyst/ionomer weight ratio was 90/10. The coating procedure was spray coating at the both laboratories. However, at DLR Oldenburg an automatic SONOTEK spray coating was used for preparing 25 and 200 cm² electrodes, while at CEA a manual spray device was used for 2 and 25 cm² electrodes size.</p>
<p>It was found that for a large electrodes production, the chloroform may lead to a better ink stability in comparison with Toluene. DLR experienced a decantation of the ink with time with the latter solvent. At CEA, such an instability was not observed, probably because, the spraying time was shorter. To circumvent this issue, IMC recommended the chloroform as the most suitable solvent.</p>
<p>Lastly, despite poor performances at the start of the project due to testing conditions in pure water electrolyte, some attempts to prepare catalyst coated membrane (CCM) was made. We succeed to prepare CCM-MEA by bar coating directly onto the membrane and by decal transfer method on Fumatech membrane. These approaches could be reconsidered for subsequent work for preparing CCM MEAs.</p>

<p>This study deals with the preparation and characterisation of catalyst-coated membranes for an alkaline water electrolysis process. For this purpose, a chloromethylated anion-selective block copolymer of styrene-ethylene-butylene-styrene with 1,4- diazabicyclo[2.2.2]octane functional groups was used both as an alkaline polymer electrolyte membrane and as an ionomer binder. Non-PGM catalysts (platinum group metals), specifically NiCo2O4 and NiFe2O4, were used on the anode and cathode side of the membrane, respectively. Air-brush deposition or computer-controlled ultrasonic dispersion of the catalytic ink were used to deposit the catalyst layers. The influence of the composition of the catalyst layer on its stability and the resulting electrolysis cell performance was investigated under typical membrane alkaline water electrolysis conditions (1–15 wt.% KOH, 45 ◦C). The optimal catalyst-to-binder ratio in the catalyst layer was identified as 93/7 using a catalyst<br>
loading of 2.5 mg cm-2 on each side of the membrane. The membrane electrode assembly prepared under optimal conditions showed high stability over 140 h at a<br>
current density of 250 mA cm-2. At this current load, the cell exhibited a voltage of 2.025 ± 0.010 V. The increase in cell voltage observed during the stability test did<br>
not exceed 1 μV h-1.<br>

<p>The porous transport layer (PTL) is one the key components in variety of gas evolving electrochemical conversion technologies from fuel cells to carbon dioxide reduction and electrolyzers. The PTL has several purposes in electrolyzers, including thermal and electrical conduction, mechanical support, pathways for delivery of reactant liquid water to the catalyst layer, and removal of gaseous phase from the reaction sites to the outlet. The importance of the PTL is shown in a number of previous studies for electrolyzers. Multifunctional PTL was developed by introducing Nickel-based micro porous layers (MPLs) on the top of stainless-steel PTL substrates using vacuum plasma spraying technique and tested as a gas diffusion layer in AEMWE. The Ni-based MPL coated PTLs were characterized by SEM, EDX and XRD and with electrolyser cell testing. This deliverable is to report about the development of improved PTL for NEWELY AEMWE cells for operation in pure water and dilute KOH solution and it reports about the finally selected PTLs for the NEWELY stack.</p>
<p>Optimized Plasma-coating of porous Nickel as microporous layer on multilayer stainless steel PTLs were demonstrated to improve performance in both cells operated in pure water as well as 0.1 M KOH solution for Catalyst-Coated-Membrane (CCM) electrodes.</p>
<p>As the project moved to Catalyst-Coated-Substrate (CCS) electrodes an option how to realize MPL coating on market-available stainless-steel PTLs of the thickness as required for the NEWELY cell was realized, however, the performance in the cell could not be evaluated due to time limitations.</p>
<p>Finally, the NEWELY stack is equipped with CCS electrodes supported on commercial stainless steel felts and carbon papers and the PTLs are commercial stainless steel multilayer filter-grids and porous graphite.</p>

<p>The polybenzimidazoles represent a large family of high-performance polymers containing benzimidazole groups as part of the structural repeat unit. New application areas in electrochemical cells and separation processes have emerged during the last two decades, which has been a major driver for the tremendous development of new polybenzimidazole chemistries and materials in recent years. This comprehensive treatise is devoted to an investigation of the structural scope of polybenzimidazole derivatives, polybenzimidazole modifications and the acid-base behavior of the resulting materials. Advantages and limitations of different synthetic procedures and pathways are analyzed, with focus on homogeneous solution polymerization. The discussion extends to the solution properties of the obtained polybenzimidazoles and the challenges that are faced in connection to molecular weight determination and processing. Methods for polybenzimidazole grafting or crosslinking, in particular by N-coupling, are reviewed and successful polymer blend strategies are identified.<br>
The amphoteric nature of the benzimidazole groups further enriches the chemistry of the polybenzimidazoles, as cationic or anionic ionenes are obtained depending on the pH. In the presence of protic acids, such as phosphoric acid, cationic ionenes in the form of protic polybenzimidazoliums are obtained. The acid sorption dramatically changes the physicochemical properties of the material, which is discussed and analyzed in detail. Cationic ionenes are also obtained by full N-alkylation of a polybenzimidazole to the corresponding poly(dialkyl benzimidazolium), which has been intensively explored as a new direction in the field of anion exchange membranes recently. In the higher end of the pH scale in aqueous hydroxide solutions, anionic ionenes in the form of polybenzimidazolides are obtained as a result of the deprotonation of the benzimidazole groups. The ionization of the polymer results in dramatically changed physicochemical properties as compared with the pristine material, which is described and discussed.<br>
From a technological point of view, performance and stability targets continue to motivate further research and development of new polybenzimidazole chemistries and energy materials The overall aim of this review is therefore to identify challenges and opportunities in this area from synthetic chemistry and materials science perspectives to serve as a solid basis for further development prospects.<br>
