abstract = {Metal-supported solid oxide fuel cells (MSCs) are promising
candidates for mobile power generators like range extenders
for battery electric vehicles due to their improved thermal
conductivity and ruggedness. The limited space available in
such vehicles heightens the need to achieve high power
densities. In the present study, a significant increase in
cell performance of the MSC concept of Plansee SE was
demonstrated by means of systematic microstructure
optimization of the complete cell architecture based on
improved processing. Thickness and roughness of
multi-layered Ni/GDC anode play a particularly important
role in improving cell performance. After several
optimization steps, a notable increase of current density
from 1.29 A/cm2 to 1.79 A/cm2 at 700 °C and 0.7 V $(+38\%)$
was achieved. Additionally, lowering the anode roughness
enables clear reduction of electrolyte thickness down to 2
μm, a starting point for the further enhancement of cell
performance.},
