Using inexpensive nickel compounds to replace costly and rare iridium for efficient alkaline membrane electrolyzers

A team from the Technical University of Berlin, HZB, IMTEK (University of Freiburg) and Siemens Energy has developed a highly efficient alkaline membrane electrolyzer that approaches the performance of established proton-exchange membrane(PEM) electrolyzers. What makes this achievement remarkable is the use of inexpensive nickel compounds for the anode catalyst, replacing costly and rare iridium.
