摘 要：This paper presents results of a comparative study of a micro-combined heat and power (CHP) unit with solid oxide fuel cell (SOFC) fed by two different fuels.For current analysis biogas and dimethyl ether (DME) were selected.Detailed model of the micro-CHP system with net power output of 3 kWel was created,based on an advanced model of the SOFC.In both power units,steam reforming was employed in order to generate hydrogen-rich gas.Reforming temperatures of 900℃ and 350℃ were selected for biogas and DME,respectively.Both systems were based on the same reference solid oxide fuel cells.Similar plant outlines was employed,with small changes to accommodate different reformer operating temperatures.
