Development and progress in manufacturing of high power density electrolyte supported cell is presented. The maximum power density increased from 529 mW/cm2 for commercial cell (Fa. Kerafol) up to 973 mW/cm2 for novel IKTS cell at 0.7V@860°C and is comparable with the performance of anode-supported SOFC cells. The changes in polarization resistance of tested cells under different conditions are discussed on basis of analysis of impedance spectra.
