Abstract

The large-scale commercialization of polymer electrolyte membrane (PEM) water electrolyzers is still constrained by their high capital cost, which is largely associated with the use of noble metal-based electrocatalysts. There is an urgent need to reduce their loading in the composition of electrocatalytic layers. In the present work, an approach of the microporous sublayer made of titanium nitride (TiN_x) and formed over the anode surface by magnetron sputtering is proposed. It contributes to an increase in the anode electrocatalyst utilization, opening up wide possibilities to reduce its loading.

在 PEM 水电解槽阳极多孔传输层表面形成的氮化钛 TiNx 子层的研究与开发

摘要聚合物电解质膜（PEM）水电解槽的大规模商业化仍然受制于其高昂的资本成本，这在很大程度上与贵金属电催化剂的使用有关。因此，迫切需要减少贵金属在电催化层中的含量。本研究提出了一种通过磁控溅射在阳极表面形成氮化钛（TiNx）微孔子层的方法。它有助于提高阳极电催化剂的利用率，为降低阳极负载量提供了广阔的可能性。
