This work aims to develop a 0-D simulation model of an hybrid SOFC-ORC system and to estimate the benefits in terms of power production respect to the fuel cell alone. Reference case is an industrial Fuel Cell system with three modules. It is a Solid Oxide high temperature Fuel Cell working at atmospheric pressure, manufactured by the Finnish company Convion Ltd. It converts the chemical energy of a biogas flow from a Waste Water Treatment Plant into thermal and electric power up to 58 kW per module and releases gas exhausts at about 220°C. Here it is supposed to use the latter for further power production by means of compatible power cycle.
