Significant reduction of the precious metal alyst loading is one of the key challenges for the commercialization of protonexchange membrane water electrolyzers. In this work we combine IrOx nanofibers with a conventional nanoparticlebased IrOx anode alyst layer. With this hybrid design we can reduce the iridium loading by more than 80% while maintaining performance. .
