Protonic ceramic fuel cells (PCFCs) are clean and efficient power generation devices operating at intermediate temperatures. However, manufacturing difficulties have limited their commercialization, especially for promising tubular PCFCs. Herein, we report a cost-effective 3D printing technique large-area PCFCs (e.g., 15.7 cm2), featured with the use of commercial raw materials, small amount binder, CO2 laser rapid in situ drying. The technical advantages enable low-cost material preparation...
Protonic ceramic fuel cells have attracted much attention due to their good performance at intermediate temperatures (400–700 °C). However, the highly resistive electrolyte-cathode interface has been discovered be a crucial obstacle inhibiting further cell improvements in performance.
