Comparative study of biogas and DME fed micro-CHP system with solid oxide fuel cell

abstractEN: 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°C and 350°C 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.score: 0collation: 53-5
