Disclosed is a fuel cell assembly in which the electrolyte and other reactants having evaporated into the fuel gas or oxidizing gas streams passing through the cells can be condensed and recovered back into the cells. This comprises a stack (1) of a plurality of fuel cells (2), each cell (2) having a pair of porous electrodes (4, 5) with an electrolyte layer (3) being sandwiched therebetween and a pair of gas guide means (7, 9) as disposed adjacent to and over said pair of porous electrodes (4, 5) for passing fuel gas (14) and oxidizing gas (15) therethrough in a direction perpendicular to each other, and a cooling means (19, 20) for cooling a part of a nongenerating zone being positioned outside the generating zone to be defined by the range of said pair of gas guide means (7, 9) overlapping with each other in the stacking direction for thereby condensing and recovering the condensable substance from the gases being guided by the gas guide means into the cells (2). The stack realizes prolongation of the operable life of the cells and increase in the power-generating efficiency of the cells. |
