The present invention relates to electrodes having Gd and Pr -doped cerium oxide (CGPO)backbones infiltrated with Sr -doped LaCoO3 (LSC) and a method to manufacture them. Pr ions have been introduced into a prefabricated CGO backbone by infiltrating Pr nitrate solution followed by high temperature firing. The high temperature firing allows the Pr ions to diffuse into the CGO backbone. The resulting backbone would then have a co-doped subsurface exhibiting electronic conductivity having improved performance when used as electrode in, e.g. a fuel cell. Remaining particles of praseodymium oxide in the surface could also be advantageous.
