Compared to significant progress in PEMFC especially regarding the utilization of complex fuels such as methanol significant progress has been made by applying spectroscopic / differential IR and spectrometric techniques to working fuel cells, the processes in solid state high temperature electrochemical cells are still a "black box". In order to identify local reaction sites, surface coverage and potential/current introduced materials and surface modifications, in situ techniques are needed to gain a better understanding of the elementary and performance limiting steps for these cells. This relates to interrelation between NOx/ O2 on cathodes but also to sulfur and carbon exposure at the anode. Past and recent activities on SOFC anodes and cathodes will be presented as well as perspectives and gaps discussed for these systems. Especially interaction between sulfur interactions with solids and surface are complex and recent and past research activities in these areas will be presented.
