Abstract
Gas-phase laser Raman spectroscopy has recently been adopted to determine the concentrations of relevant gaseous species within the anode flow channel with high spatial and temporal resolution during operation at technically relevant operating conditions. The paper describes the configuration of an optically accessible SOFC, the laser system and optical setup for 1 D Raman spectroscopy as well as the challenges associated with the measurements of an electrolyte supported cell of a size of 50 x 50 mm2. At different operating conditions Raman spectra were recorded and concentration profiles of gas species along the flow path in the anode were determined demonstrating this new experimental approach for a better understanding of SOFC processes.
