The generation of electrical energy from biogas is state of the art. One option is the application of fuel cells for generating electrical energy. Due to their construction, the materials used and their mode of operation, solid oxide fuel cells (SOFCs) are particularly suitable. The primary problem in the operation of SOFCs using biogas is H 2 S. The goal of this work is to investigate the possible effects of ammonia on different sorbents that have already successfully been used for the desulfurization of biogas. The H 2 S adsorption capacity of four commercially available sorbents in the presence of NH 3 was investigated as well as the influence of an upstream NH 3 removal. The CuO‐MnO‐based sorbent showed the best performance related to sulfur uptake.
