Abstract: The present invention is to provide, in a combined system of a bioethanol producing device and an SOFC, a method that is capable of further enhancing the electric power generation efficiency of the SOFC, and is also capable of achieving further reduction of the energy required for distillation of the fermented liquid. A part of an anode off-gas is refluxed to the water-containing ethanol vapor line from the mash column to the reforming device at a reflux ratio ((flow rate of reflux gas)/(flow rate of (anode off-gas)−(reflux gas))) of from 1 to 2. The ethanol concentration of the water-containing ethanol vapor is controlled by refluxing, to a range of from 25 to 35% by weight with water contained in the anode off-gas of the solid oxide fuel cell.

Abstract: A fuel cell system includes a reformer and a plurality of fuel cells of solid oxide. The reformer reforms raw fuel to generate fuel gas. The plurality of fuel cells generates electric power by using the fuel gas and oxidant gas. The plurality of fuel cells is arranged in the up-down direction and the right-left direction. The reformer has a cell facing face that faces any of the plurality of fuel cells in the back-and-forth direction. This configuration improves temperature uniformity among the plurality of fuel cells, and as a result, suppresses or prevents a decrease in the power generation efficiency of the fuel cell system.
