Abstract
An oxygen reduction reaction catalyst (ORR) and a method for making the catalyst are provided. The method may include depositing (e.g., by PVD) conductive catalyst material onto a non-conductive substrate, such as particles or powder, to form an intermediate ORR catalyst. The intermediate ORR catalyst may then be heat treated and another deposition process may be performed to form a thin, electrically interconnected catalyst network layer overlying the non-conductive substrate. The catalyst material may include, for example, platinum, gold, or other platinum group or noble metals, or alloys thereof. The non-conductive substrate may be a ceramic, for example, yttria-stabilized zirconia (YSZ).
