This work deals with SOFC single cell tests using neodymium nickelate Nd1.95NiO4 + δ as cathode material. This MIEC oxide exhibits high values of both surface exchange coefficient (k) and oxygen diffusion coefficient (D*), as well as high electronic conductivity, which result in an enhanced electrochemical activity with respect to classical materials...
