Catalyst Utilization for AEM Electrolysers

The primary source of green hydrogen, faces several barriers. One of the main issues is that it relies heavily on costly and scarce noble metals, namely platinum, iridium, and ruthenium. The utilization of these metals brings into question their supply chain availability, sustainability in green hydrogen projects, and overall cost. On the other hand, AEM electrolysers can operate with noble metal-free catalysts since they do not provide any advantage compared to non-noble-based catalysts such as Ni, Co, and Fe in an alkaline media. However, scaling up the AEM electrolyser systems from a benchmark to a commercial scale for widespread use presents challenges in maintaining catalyst performance and durability at larger sizes.
Utilizing nanostructures is a solution that simultaneously addresses stability and efficiency concerns. This sturdy and highly permeable catalyst can significantly enhance surface area, which is vital for improving efficiency. The collaboration between the Cipher Neutron, a commercial AEM producer, and the catalyst development research group at the University of Alberta is an ideal partnership to overcome the obstacles of AEM commercialization and work towards the common goal of producing green hydrogen in an environmentally friendly manner which is in line with the hydrogen roadmap of Alberta.
