abstract = {La0.58Sr0.4Co0.2Fe0.8O3-δ (LSCF) cathodes on
metal-supported solid oxide fuel cells (MSCs) were
fabricated by a novel sinteringapproach and
electrochemically tested in single-cell measurements. The
sintering of cathodes on complete cells was performedunder
argon atmosphere at 950◦C in order to prevent strong
oxidation of the metallic support. During this sintering
process, aphase decomposition of LSCF occurred, which was
found to be reversible upon heating in ambient air. The
observed performanceincrease of MSCs with cathodes sintered
ex situ, compared to cells processed under standard
conditions, revealed a beneficial effectof the increased
sintering temperature on cell performance. At 750◦C and
0.7 V a current density of 0.96 A/cm2 was achieved.A
stronger adherence of the cathodes sintered ex situ was
observed after single-cell measurements. In additional
experiments,La0.58Sr0.4CoO3-δ (LSC) was applied as an
alternative cathode for MSCs. These cells were activated in
situ at 850◦C due to thelower thermochemical stability of
LSC and indicated potential for further improvement of the
cell performance. The successfulelectrochemical
characterization of the cells with LSCF cathodes sintered ex
situ confirmed the applicability of the novel
sinteringprocedure as well as the improved adherence
achieved by the optimized processing.},
