Large-area anode-supported protonic ceramic fuel cells combining with multilayer-tape casting and hot-pressing lamination technology

Anode-supported protonic ceramic fuel cells (PCFCs) have many advantages such as the excellent performance and durability at lower temperatures. However, the fabrication of large-area PCFCs is still a big challenge. In this work, the anode supported 10 x 10 cm2 PCFCs with BaZr0.1Ce0.7Y0.1Yb0.1O3-delta (BZCYYb) electrolyte are fabri-cated by an optimized sintering process combining with multilayer-tape casting and hot-pressing lamination technology. Through optimizing the sintering shrinkage and thermal expansion behavior, anode supported large -area PCFCs with dense BZCYYb electrolyte are obtained with optimal sintering process. The maximum power density of the cell using H2 as fuel reaches 400 mW/cm2 at 700 degrees C. The cell also shows a good thermal cycling performance and durability in 425 h test. Preliminary experimental results indicate that the fabrication tech-nology with multilayer-tape casting and hot-pressing lamination is successful for large-area PCFCs, which can improve the cell fabrication efficiency and provide positive reference for large-area PCFCs.
