給装置を提供することを目的とするものである。Incidentally, the composition of the fuel gas is such that hydrogen having a molecular weight of 2 is about 80%.
%, Carbon dioxide with a molecular weight of 44 is about 20%. This fuel gas slowly rises in the main supply pipe 2 and the cells
Although the temperature stacked at a height of 5 m is supplied through the supply manifold 3 into the battery stack 1 having a temperature of 140 to 190 ° C., a large amount of light hydrogen is supplied to the upper portion of the supply manifold 3 while flowing through the tubes. The top of the stack 1 tends to be a hydrogen-rich fuel gas supply. On the other hand, the composition of air is about 20% of oxygen having a molecular weight of 32 and about 80% of nitrogen having a molecular weight of 24. Therefore, in the air supply, a large amount of heavy oxygen is supplied to the lower portion of the inlet manifold 7, and the lower portion of the battery stack 1 tends to supply oxygen-rich air. FIG. 4 is a diagram showing such a tendency, and FIG. 4 (A)
Is the hydrogen concentration in the inlet fuel gas (horizontal axis) and the cell stack 1
FIG. 4 (B) similarly shows the relationship between the oxygen concentration (horizontal axis) and the height position of the battery stack 1. As described above, when the fuel gas having a small hydrogen component is supplied to the lower portion of the battery stack 1 and the air having a small oxygen component is supplied to the upper portion of the battery stack 1, each component has the same effect as the gas shortage. In the conventional fuel cell, there is a problem that the life of the battery is shortened at the uppermost portion and the lowermost portion of the cell stack 1. An object of the present invention is to provide a reaction gas replenishing device for a fuel cell, which alleviates the above-described problems based on the characteristics of hydrogen and oxygen and improves the life of the battery.
