Abstract Solid oxide cells (SOC) are an efficient and cost-effective energy conversion technology able to operate reversibly in fuel cell electrolysis mode. Electrolyte-supported SOC have been recently fabricated employing 3D printing generate unique geometries with never-explored capabilities. However, the use of state-of-the-art electrolyte based on yttria-stabilized zirconia limits current performance such printed devices due a limited oxide-ion conductivity. In last years, alternative...
Abstract Mixed ionic and electronic conductor double perovskites are very promising oxygen electrode materials for solid oxide cell technology. However, understanding their specific kinetic mechanism is a fundamental preliminary step towards detecting the best reachable performance, optimising operation conditions architecture. Indeed, contributions of different rate-determining steps can vary as function working point. In this framework, after detailed experimental campaign devoted to study...
