Abstract

Catalytic coatings for electrodes of fuel cells and water electrlyzers with a polymeric proton-exchange membrane were prepared by magnetron sputtering of composite targets and studied. The noble metals platinum and iridium were used as inserts into the base targets made of graphite, molybdenum, titanium, or nickel. The effects that parameters of different processes occurring in magnetron sputtering have on the electrochemical behavior and structural properties of catalytic compositions are investigated. The prepared coatings display high catalytic activity. We discuss the feasibility to use magnetron sputtering for fabrication of thin nanostructured catalytic compositions as part of industrial technology of fuel cells and electrolyzers with proton-exchange membrane and low noble metal contents.

通过复合靶的磁控溅射制备具有质子交换膜的燃料电池和水电解槽电极的催化组合物

摘要

通过复合靶的磁控溅射制备了具有聚合物质子交换膜的燃料电池和水电解槽电极的催化涂层并进行了研究。贵金属铂和铱被用作插入由石墨、钼、钛或镍制成的基靶中。研究了磁控溅射中不同工艺的参数对催化组合物的电化学行为和结构特性的影响。制备的涂层显示出高催化活性。我们讨论了使用磁控溅射制造薄纳米结构催化组合物作为具有质子交换膜和低贵金属含量的燃料电池和电解槽工业技术的一部分的可行性。
