3rd SCIENTIFIC PUBLICATION IN JOURNAL OF POWER SOURCES

We are proud to announce that the article “Optimization of the membrane electrode assembly for an alkaline water electrolyser based on the catalyst-coated membrane” has been published in open access on the Journal of Power Sources.

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 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 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 not exceed 1 μV h-1.

NEWELY PRESENTED AT MODVAL2022

NEWELY’s researchers Ronit Kumar Panda, Guillaume Serre, Pascal Schott, Yann Bultel presented at Modval2022 their modelling work on the NEWELY electrolyser.

The oral presentation detailed the need for modelling the AEM water electrolysis and the phenomenon associated with it. The context of lumped parameter based modelling approach and initial results obtained were discussed to better understand the performance of AEMWE.

FOURTH PROJECT MEETING

Fourth semiannual meeting

2022 will be an exciting year for the NEWELY project! Most of the testing on the stack and the membranes will be concluded and new publications are expected by the end of the year.

The NEWELY’s Consortium met online today to align on the status of the activities and to plan the next steps to meet the targeted objectives.  

A new editorial plan has been created to post monthly updates on the project and to keep our audience informed about the latest development of the project.

Stay tuned to discover more!

THE AEM HUB AND CLEAN HYDROGEN PARTNERSHIP DISCUSS ABOUT FUTURE SINERGIES FOR AEMEL R&D

AEM Hub and CHP

On 28 Jan 2022, the three projects of the AEM Hub (ANIONE, CHANNEL and NEWELY) got together with the Clean Hydrogen JU experts to discuss the progress and challenges of the projects in the first two years and identify synergies and solutions for the last phase of the projects. The workshop kicked off with a short presentation from each of the project Coordinators who presented the status and challenges faced.

The main challenges identified are:

  • Concentrations of KOH between 0 and 1 M were studied in the project having influence on performance and lifetime. The ideal concentration depends on the system and still needs to be identified and its effect needs to be better understood;
  • The various AEM membranes and ionomers are varying in chemical and thermal stability;
  • Need for harmonized procedures and baseline materials to properly access and compare the progress of alternative materials:
  • Progress of the technology is a compromise between performance and durability.

The synergies that are planned to be exploited during 2022 are:

  • Revision and update of the joint testing protocols;
  • Use of the same cell for testing in the 3 projects;
  • Investigate possibility of round robin testing;
  • Writing of a joint publication on the common knowledge generated.
  • The joint effort done by the three projects in the AEM Hub is expected to bring new fruitful results during 2022.

Stay tuned for updates!

NEWELY & the AEM HUB PARTICIPATE AT FCH JU PROGRAMME REVIEW DAY

The NEWELY Project together with its siblings CHANNEL and the ANIONE projects took part to the panel session on Next Generation Electrolyzers at the Programme Review Days 2021. The PRDs have been organized by FCH JU as the last event of the European Hydrogen Week.

The three projects form the AEM Hub, joining forces to develop testing standard and common language for advancing AEMEL research in Europe. The three projects are working to demonstrate 2 kW AEM WE stack prototypes operating at high pressure for green hydrogen production.

The three projects will meet online in joint workshop at the end of January to further advance their common activities on testing protocols.

NEWELY WILL BE PRESENTED AT FCH JU PROGRAMME REVIEW DAYS

On December 2 at 2.30 pm, our coordinator Aldo Gago will present the progress of the NEWELY project in the Panel Session on “Next generation electrolysers” at the FCH JU Programme Review Days.

This two-days event will kick-close the EU Hydrogen week and, following the tradition of the past 11 years, will provide an excellent visibility platform for more than 60 projects currently on-going under FCH JU.

More than 53 selected projects and initiatives will have the opportunity to present their progress, obtain feedback, exchange ideas and best practices on the latest technological developments in the sector. Throughout the entire event we will also make available for download scientific posters for all FCH JU funded projects.

Join us on 2 and 3 December to hear Europe’s leading hydrogen projects and discover updates about the technology!

2nd SCIENTIFIC PUBLICATION IN JOURNAL OF MEMBRANE SCIENCE

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).
