Ni cermet anodes are commonly used in solid oxide fuel cells (SOFCs) [1][2][3][4], but there has been considerable interest in alternative oxide-based anodes [5]. The motivation for the alternative materials is to avoid problems with the Ni-based anodes, including susceptibility to coking in hydroca
In order to compare the electrochemical performance of Ce 0.9 Gd 0.1 O 2Àd (CGO) in various fuels, impedance spectroscopy measurements were carried out in the atmospheres containing H 2 , CO, CO 2 , CH 4 , N 2 at various compositions, in the temperature range 650 8C to 850 8C. Ohmic loss and polariz
