Large Area High-Performance Thin Film Solid Oxide Fuel Cell with Nanoscale Anode Functional Layer by Scalable Reactive Sputtering.

ABSTRACT: For high-performance thin-film solid oxide cells (TF-SOCs), a nanostructured anode functional layer (n-AFL) that can prolong the triple-phase boundary (TPB) is crucial, particularly for low-temperature operation. However, the implementation of n-AFL (usually >1 µm in thickness) has critical issues in scale-up and productivity. Here, the study successfully demonstrates a large-area, high-performance TF-SOFC with an n-AFL fabricated via mass-production-compatible reactive magnetron sputtering. The cell with optimized n-AFL by adjusting crucial reactive-sputtering process parameters, i.e., oxygen partial pressure and sputtering power, shows superior performance compared to that of the cell without n-AFL: the reduction both in ohmic and anodic polarization resistances by 63% and 34%, respectiv
