We are pleased to announce that the open access version of the article PBI nanofiber mat-reinforced anion exchange membranes with covalently linked interfaces for use in water electrolysers is now available online.
In this work, we approach the issue of AEM reinforcing by pore filling polybenzimidazole nanofiber mats with the bromomethylated precursor of mTPN, an ultra-stable AEM material. During drying, a covalent interaction between support (PBI amine groups) and matrix (-CH2Br) is established. After quaternization, the optimized PBI/mTPN-50.120 composite membrane still shows a high conductivity of 62 mS cm−1, but 37% reduced length swelling in comparison to the non-reinforced membrane. Tensile strength and Young’s modulus increase 17% and 56% to 49 MPa and 680 MPa, respectively. In an electrolyser, a stable voltage of 1.98V at 0.25 A cm−2 was achieved, and no change in membrane resistance was observed over the test time of 200 h (50 °C, 1 M KOH, catalysts based on Ni/Fe and Mo).

The NEWELY project will participate to the webinar on Anion Exchange Membrane Electrolysers organized by FCH JU. The webinar is scheduled for Tuesday 6 July, 2021 | 14:00 – 15:30.
Since 2020 the FCH JU has supported three cutting-edge projects on this research field: ANIONE, CHANNEL and NEWELY.
The projects will be showcasing their targets, achievements and remaining challenges in developing 2kW prototypes of AEMEL. This will be followed by a discussion on the steps needed to upscale AEMEL including EU support.
Registration is required to join the webinar.

The NEWELY’s consortium has met online to share the latest updates on the R&D activities for the prototype construction.
There are innovations deriving from the activities on the membranes, cell and electrodes. These will make NEWELY’ s a promising project for the uptake of Anion Exchange Membrane Water Electrolysers.
More information will be posted in the coming weeks. Stay tuned!
The NEWELY Project has just entered the second project year. We expect a year full of activities that will bring NEWELY a step further in the development of the prototype for next generation of water electrolyser based on AEMs.
The third project meeting is scheduled for the 26th of February 2021. The Consortium will share updates on the research activities and the preliminary test results on the membranes and electrodes.

The scientific paper “Overview: State-of-the art commercial membranes for anion exchange membrane water electrolysis” has been published on the last issue (31 July 2020) of the Journal of Electrochemical Energy Conversion and Storage.
The paper presents target values and technical requirements for Anion Exchange Membranes (AEMs), discusses the chemical structures involved and the related degradation pathways, and gives an overview over the most prominent and promising commercial AEMs (Fumatech Fumasep® FAA3, Tokuyama A201, Ionomr Aemion™, Dioxide materials Sustainion®, and membranes commercialized by Orion Polymer), and reviews their properties and performances of water electrolyzers using these membranes.
