Achieving performance and longevity with butane-operated low-temperature solid oxide fuel cells using low-cost Cu and CeO2 catalysts
Autor: Jong-Ho Lee, Kyung Joong Yoon, Ho-Il Ji, Hyoungchul Kim, Cam-Anh Thieu, Ji-Won Son, Sungeun Yang
Publikováno v: Journal of Materials Chemistry A. 10:2460-2473
The use of thin-film solid oxide fuel cells (TF-SOFCs) can effectively lower the operating temperature of a typical solid oxide fuel cell (SOFC) below 600 °C, while maintaining high efficiency and using low-cost catalysts. However, the fuel flexibil
