This paper investigates the potential of a biogas-powered 2,8 kWeSOFC pilot plant constructed and operated in Mataró WWTP (NE Spain) for 18 months within the BIOCELL and the MCFC-CONTEX projects. The biogas treatment was based on a biotrickling filter and a polishing stage, with removal efficiencies greater than 99% and achieving contaminant's concentration below the fuel cell limit. The SOFC unit consisted of an electrochemical train and an after-burner. Therefore the ratio biogas-to-burner/biogas-to-stack must be optimized. Results showed that this value should be between 25% and 50% in order to optimize the overall electrical efficiency, reaching values of 24-33%, which is a very promising and optimistic result for the SOFC technology.
