Theme 4 : Metal complexes for H2 production

Ally Aukauloo, Marie Sircoglou


The proton exchange membrane  (PEM) water electrolysis has a number of advantages over the traditional water-alkaline such as designing smaller device for the production of hydrogen fuel for domestic end-uses, a high degree of purity of the gases, the possibility to compress gases within the installation. The main drawback comes from the fact that it is an expensive technology. The replacement of platinum-family catalysts and expensive solid polymer electrolyte remain challenging issues. We are involved in development of molecular based complexes with first row transition ions in view to replace the noble based catalyst at the cathode of a PEM water electrolyser for the hydrogen evolution reaction (HER).
