During the final phase, the content of Platinum Group Metal (PGM) was reduced from 200 to 90 µg cm-2 at the cathode of an Anion Exchange Membrane Electrolyser (AEMEL) and paired with a PGM-free anode, while keeping the performance high. Similarly, the PGM content at the anode of an AEM Fuel Cell (AEMFC) was reduced from 600 to 125 µg cm-2 and paired with a PGM-free cathode, while keeping the performance high.

After 30 months of project, the progress is in track with the initial schedule. Two milestones were reached during the second period (MS1 on AEM conductivity & stability and MS2 on bipolar membrane conductivity) while MS3 on AEMFC performance (0.5 W cm-2 peak power with air feed & PGM loading < 80 μg cm2) has been achieved in terms of power performance but at PGM loading above the target, due to the need for PGM at the anode. The advent of CRM-free HER/HOR catalysts with high activity is now key to realize the full potential of AEM-based devices.

During the first 18 months, activities were initiated in the four technical work packages. Harmonised testing protocols and stage gates for subcomponents were defined in WP2.
In WP3, two novel Critical Raw Materials (CRM)-free catalysts for O2 reduction and evolution reactions have reached the internal stage gates for transfer to WP5 (cell design & cell testing), while a CRM-lean catalyst reached the stage gates for H2 oxidation & evolution reactions.
In WP4, a novel test protocol for anion-exchange ionomers revealed the critical effect of water content in the electrolyte on the degradation rate, of importance to predict an operating device's durability.
In WP5, Anion Exchange Membrane ELectrolyser (AEMEL) performance was benchmarked with reference materials Platinum Group Metals (PGM) catalysts and the effect of operating conditions investigated. The optimised initial performance is close to the project target.
The next step will focus on the integration of (PGM)-free catalysts in the device.
