Proton exchange membrane water electrolysers with thin film nanostructured electrodes

点击翻译按钮获取中文摘要

The biggest challenge with current proton exchange membrane water electrolysers (PEMWE) is their poor power performance and durability, which is mainly caused by large mass transfer losses and degradation of the electrode structure from the random electrode structure from catalyst nanoparticles. In this PhD project, we'll develop a new generation of catalyst electrodes from aligned IrO2- and metal oxide-based nanowires for PEMWE applications, taking the advantages of the high stability of nanowires and the boosted mass transfer characteristics of the unique thin catalyst layers from nanowire arrays.
