      abstract     = {In this study, cathode performance of cost-effective inert
                      substrate-supported solid oxide fuel cells fabricated by a
                      single step cosintering process is investigated. The
                      polarization resistance of cosintered inert
                      substrate-supported cathode symmetrical cells (ISC) is
                      compared with the polarization resistance of
                      electrolyte-supported symmetrical cells (ESC) prepared by
                      post- and cosintering. ESC prepared by cosintering have
                      similar polarization resistance than ESC prepared by
                      post-firing due to the addition of pore formers. However,
                      the implementation of a porous inert substrate increases the
                      polarization resistance. Analysis of electrochemical
                      impedance spectra could exclude a gas-phase diffusion
                      limitation due to the porous substrate. Time-of-Flight
                      secondary ion mass spectrometry (ToF-SIMS) reveals an
                      accumulation of zinc, magnesium and silicon on the inner
                      pore surface of the cathode layer. Thermodynamic
                      calculations confirm desorption of these elements from the
                      silicate substrate during the cosintering. In addition, a
                      zinc manganite spinel is detected in the cathode layer via
                      confocal Raman spectroscopy, which indicates a reaction
                      between the cathode material and zinc. The larger cathode
                      polarization resistance of the inert substrate-supported
                      cell is attributed to microstructural changes and the
                      coverage of the cathode surface.},
