Solid oxide fuel cells are a promising opportunity in a wide range of applications for environmentally friendly energy conversion, from different types of fuels as natural gas or hydrogen, direct into electrical power. Solid oxide fuel cells (SOFSs) are not limited to the Carnot cycle of heat engines and greenhouse gas emission is much lower than that of today used power generators.

Tobias` project is dealing with Sr-doped lanthanum manganite (LSM) which is a widely used cathode material in SOFCs. Despite being the best investigated perovskite material for SOFCs the contributions of the different reaction mechanisms - and the parameters affecting their individual relevance - to the total oxygen reduction rate are still under debate. The goal of this PhD thesis is the clear identification of the rate limiting elementary step and its determining factors.
