Understanding redox cycling behavior of Ni–YSZ anodes at 500 °C in solid oxide fuel cells by electrochemical impedance analysis

Autor: Jeong Hwa Park, Kang Taek Lee, Ha-Ni Im

Publikováno v: Journal of the Korean Ceramic Society. 58:606-613

Solid oxide fuel cells (SOFCs) are promising energy conversion devices because of their high electrical efficiency, even for small power systems. However, when the anode is exposed to reduction and oxidation (redox) cycles, the Ni phase causes a larg

Ultra-fast fabrication of anode-supported solid oxide fuel cells via microwave-assisted sintering technology

Autor: Kyeong Joon Kim, Jeong Hwa Park, Kang Taek Lee

Publikováno v: Korean Journal of Chemical Engineering. 37:1436-1439

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 comp
