GENERATING DEVICE OF MOLTEN CARBONATE FUEL CELL

Japanese Patent JP3407311

B2

PURPOSE: To make the battery voltage of the upstream part and the downstream part constant by connecting plural fuel cells having the same electrode area in series, and while electrically connecting them in parallel with each other, and supplying the fuel gas from a reform chamber to the anode of the upstream battery, and after the utilization there, supplying the fuel gas to the anode of the downstream battery.
CONSTITUTION: An upstream and a downstream fuel cells I, II are formed so as to have the same electrode area to make the flowing speed of the gas flowing inside of the cells constant in the upstream battery I and the downstream battery II. But, since the fuel is consumed in the battery I, gas density of the battery I and the battery II is different from each other. Namely, the density of the upstream part is high and the density of the downstream part is low, and the current density thereof is different from each other. In the case of a high density, since a large quantity of current is flowed to make the current density large, and in the case of a low density, since the current is reduced to make the current density small. Consequently, the batteries I, II are electrically connected not in series but in parallel with each other, and the current value of the upstream part and the downstream part are set separately from each other to maintain the voltage of the batteries I, II constant.
