Abstract: Metal-supported solid oxide fuel cells (MSCs) are promisingcandidates for non-stationary applications like auxiliary powerunits (APUs) in heavy duty trucks or range extender systems forbattery electric vehicles. Due to limited space available forintegrating such systems especially in passenger cars, achievinghigh power density of MSCs is essential. The MSC concept ofPlansee SE, Austria was stepwise optimized by improvedprocessing of the electrodes and tailoring of the interfaces.Variations of cathode composition and sintering conditions wereinvestigated. Using LSC or LSC/GDC cathodes and Ni/GDCanodes with higher electrochemically active volume increased thecell performance significantly. Moreover, reducing the electrolyteto 2 μm resulted in further improvement of the performance.Finally, preliminary results of long-term operation of the PlanseeMSC for more than 1.000 h at 700 °C and 300 mA cm-2, as well aspost-mortem analyses, are presented.
