                      with cathodes made of La0.58Sr0.4Fe0.8Ni0.2O3-delta,

                      La0.58Sr0.4Fe0.6Cu0.2Co0.2O3-delta,
                      La0.58Sr0.4Fe0.7Cu0.1Co0.2O3-delta, and La2Ni0.6Cu0.4O4 has
                      been investigated. As reference, electrochemical data from
                      cells with La0.58Sr0.4Co0.2Fe0.8O3-delta cathodes were taken
                      into account. The cathode layers were sintered at various
                      temperatures. After testing, cross-sectional analyses were
                      made in order to investigate microstructural changes in the
                      various layers. Electrochemical tests have shown that only
                      cells with a non-sintered Cu-containing cathode or with a
                      similar cathode treated with relatively low sintering
                      temperatures can be considered for SOFC applications.
                      However, it was clear that the tested cells with cathodes
                      including Cu and/or Ni showed electrochemical performance
                      which was always lower than that of reference cells with
                      La0.58Sr0.4Co0.2Fe0.8O3-delta cathode. No electrochemical
                      measurements were possible with cathodes sintered at or
                      above 1000 degrees C. Cross-sectional analyses revealed that
                      in all these cases the presence of Cu exhibited severe
                      chemical interaction with the electrolyte. In addition,
                      several undesired phases were formed in the cathode as well
                      as in the diffusion barrier layer. The extent of these
                      phases and the interaction with the electrolyte layer
                      increased with increasing sintering temperature. [DOI:
