Abstract
We demonstrate ultra-fast fabrication of anode-supported solid oxide fuel cells (SOFCs) using microwave-assisted sintering technology. Due to the nature of microwaves that transfers heat directly into the material, the SOFC sintering process was completed within 8 h, ∼ six times faster compared to a conventional sintering process (∼47 h). Despite extremely rapid processing time, the microstructure of the SOFC fabricated by microwave-assisted sintering (M-SOFC) was almost identical to that of the conventionally sintered SOFC. Moreover, the electrochemical performance of the M-SOFC at 750 °C was 0.52 W/cm2 in peak power density, which is even higher than that of the conventionally sintered sample (0.49W/cm2). Thus, our results demonstrate that the ultra-fast microwave-assisted sintering process is a highly effective and practically promising technology for fabricating high performance SOFCs. © 2020, The Korean Institute of Chemical Engineers.
