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/cm 2 in peak power density, which is even higher than that of the conventionally sintered sample (0.49W/cm 2 ). 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.

通过微波辅助烧结技术超快速制造阳极支撑的固体氧化物燃料电池

我们展示了使用微波辅助烧结技术超快速制造阳极支撑的固体氧化物燃料电池 (SOFC)。由于微波的性质将热量直接传递到材料中，SOFC 烧结过程在 8 小时内完成，与传统烧结过程（约 47 小时）相比快了约 6 倍。尽管加工时间极快，但通过微波辅助烧结 (M-SOFC) 制造的 SOFC 的微观结构几乎与传统烧结 SOFC 的微观结构相同。此外，M-SOFC 在 750°C 下的电化学性能峰值功率密度为 0.52 W/cm 2 ，甚至高于传统烧结样品的电化学性能（0.49W/cm 2 ）。因此，
