Stable ceria-based electrolytes for intermediate temperature-solid oxide fuel cells via hafnium oxide blocking layer
Autor: Minjae Shin, You-Dong Kim, Jung Hyun Kim, Ja-Yoon Yang, Muhammad Saqib, John-In Lee, Ji-Seop Shin, Hyung-Tae Lim, Jun-Young Park
Publikováno v: Journal of Alloys and Compounds. 779:121-128
The electronic loss of ceria-based electrolytes is caused by the reduction of ceria at low oxygen partial pressure for intermediate temperature-solid oxide fuel cells. To address this issue, a thin hafnium oxide layer is deposited at the interface be
