摘要： The invention is directed to iridium oxide based catalysts for use as anode catalysts in PEM water electrolysis. The claimed composite catalyst materials comprise iridium oxide (IrO 2 ) and optionally ruthenium oxide (RuO 2 ) in combination with a high surface area inorganic oxide (for example TiO 2 , A1 2 O 3 , ZrO 2 and mixtures thereof). The inorganic oxide has a BET surface area in the range of 50 to 400 m 2 /g, a water solubility of lower than 0,15 g/l and is present in a quantity of less than 20 wt.% based on the total weight of the catalyst. The claimed catalyst materials are characterised by a low oxygen overvoltage and long lifetime in water electrolysis. The catalysts are used in electrodes, catalyst-coated membranes and membrane-electrode-assemblies for PEM electrolyzers as well as in regenerative fuel cells (RFC), sensors, and other electrochemical devices.
