ABSTRACT: Developing stable, critical raw material lean catalysts for the OER is essential for low-cost green hydrogen production. In this study, dense, polished pellets of Sr0.98Ti0.7Fe0.25Ni0.05O3 (STFNO) were employed as a model system to investigate intrinsic OER activity and stability under industrially relevant conditions. The well-defined surface and controlled interface between the sample and electrolyte represent a more fundamental approach to studying catalytic performance. Testing was conducted at elevated temperatures up to 150 °C and at a pressure of 50 bar, offering unique insights into catalytic activity and stability under harsh conditions. STFNO demonstrated excellent stability during prolonged testing and high catalytic activit
