Abstract

Abstract : In article number 2002926, Marcelo Carmo and co‐workers use a very simple and scalable method to protect titanium porous transport layers (PTLs) from passivation by sputtering very thin layers of Ir or Pt onto PTLs. 4000 h stable durability profiles are achieved when PTLs are coated with only 0.1 mg cm −2 of Pt or Ir. The results of this work show how the interface of a well‐protected titanium fiber behaves against passivation after long‐term operation under real electrolysis conditions.
