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 criti...

| description | 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%, respectively, and the improvement in maximum power density by 89% (0.705 W cm−2 vs 1.333 W cm−2) at 650 °C. When employed in large‐scale cell (4 × 4 cm2), the TF‐SOFC with n‐AFL showed 19.4 W at 650 °C. |
