Abstract

A fuel electrode consisting of particles of Ni and mixed conductor, Nd-doped ceria (NDC) has been developed. The electrode resistance decreased with decreasing the oxygen partial pressure lower than 10−11 atm, where the electronic conduction is predominant for NDC. This decrease in the resistance could be attributed to an increase in the triple phase boundary caused by an increase in electronic conductivity of NDC.
