Development of alternative fuel electrodes for upgrading biogas through CO2
Abstract
Due to the large amount of carbon dioxide in biogas reducing its flame velocity, flammability range, heating value as well as power output, the biogas must be upgraded to a higher value product. In this paper, direct feeding of simulated biogas to SOECs has been investigated; in particular, two different fuel electrode materials which are nickel with 8% yttrium-stabilized zirconia (Ni-YSZ) and La0.43Ca0.37Ni0.05Ti0.95O3- (LCNT) incorporated with 8 mol% yttrium-stabilized zirconia (8YSZ) electrolyte and La1− xSrxMnO3 perovskite (LSM)-yttria-stabilized zirconia (YSZ) composite air electrode have been tested. Both cells demonstrate feasible way for biogas electrolysis.
