      abstract     = {Cathode processing is one of the main challenges in the
                      manufacturing of metal-supported solid oxide fuel cells
                      (MSCs). Cathodesintering in ambient air is not applicable to
                      MSCs, as oxidation of the metal substrate and the metallic
                      Ni of the anode damagesthe cell. A recently developed ex
                      situ sintering procedure for the LSCF cathode in an argon
                      atmosphere was shown to significantlyimprove cathode
                      adherence. However, the stability of the sintered cathode
                      layer posed a challenge during storage in ambient air. In
                      thepresent work, adapting the ex situ sintering approach to
                      LSC/GDC dual-phase cathodes not only enabled the ex situ
                      sintering processto be applied to LSC-based cathodes, but
                      also resulted in the superior stability of the cathode after
                      sintering. Despite the hygroscopicproperties of the
                      partially decomposed perovskite, LSC/GDC dual-phase cathodes
                      were shown to withstand more than 1 year ofstorage in
                      ambient air without failure. Electrochemical single-cell
                      measurements and post-test analysis confirmed the
                      reversibilityof phase transformations and the
                      electrochemical activity of such dual-phase cathodes.
