Abstract
The invention relates to a porous material in the form of microspheres based on iridium and/or iridium oxide, its preparation process, its use as anodic catalyst in a water electrolyser based on a solid polymer electrolyte, also called PEM water electrolyser (with PEM meaning “Proton Exchange Membrane” or “Polymer Electrolyte Membrane”) or for the manufacture of light-emitting diodes for various electronic devices or for cars, and a PEM water electrolyser comprising such a material as an anode catalyst.
