In order to optimize solid oxide fuel cells for operation in highly efficient systems, a new measuring system with segmented cells has been developed, which allows us to determine local effects and to identify critical operating parameters during operation. The setup of the measuring system and experimental results for two examples—influence of hydrogen content and fuel utilization on performance and influence of load on power density and fuel utilization at operation with gasoline reformate as fuel—are presented to demonstrate the potential of the spatially resolved measuring technique.
