Improving the performance of the Ba0.5Sr0.5Co0.8Fe0.2O3-δ cathode for proton-conducting SOFCs by microwave sintering
Source abstract
Abstract
In this study, we prepared a BaSrCoFeO (BSCF) cathode layer for proton-conducting solid oxide fuel cells using microwave sintering. Unlike traditional sintering, which is carried out at 1000 °C for a few hours, the microwave sintering method allows the BSCF cathode layer to adhere well with the electrolyte layer after sintering at 900 °C for 10 min. This strategy helps the cathode layer maintain a microstructure favourable for cathode reactions and mitigate the potential diffusion of elements between it and the BaZrCeYO electrolyte, leading to improved cell resistance. The cell with the BSCF cathode layer sintered by the microwave method has a power output of 0.96 W cm at 700 °C, while the power output for the cell with a conventionally sintered cathode is 0.33 W cm.
