Název v původním jazyce

Influence of the gas diffusion layer material and method of catalyst deposition on performance of anode for PEM water electrolysis

Popis výsledku v původním jazyce

Hydrogen is foreseen as an energy carrier in the future energy systems. Water electrolysis with a proton exchange membrane represents an effective way of its production, although the high price of electro-catalysts still obstructs its commercialization.The aim of this study was to optimize the preparation of anodes based on IrO2 for this technology in order to reduce the catalyst loading necessary for sufficient process intensity. Effect of the gas diffusion layer material and its temperature during acatalytic layer deposition were in the centre of interest. Both studied material, i.e. tantalum coated steel felt and titanium felt, were proved to be suitable for this particular application. Heating of a felt during the spraying of the catalyst suspension resulted in higher utilization of the IrO2 catalyst. It is due to its localization closer to the membrane-electrode interface.
