PURPOSE:To prevent the deterioration of cell performance by monitoring moisture in inert gas supplied to a cell, and restraining the moisture in the gas to given amount after the total amount of reaction gas is substituted with the inert gas. CONSTITUTION:When the supply starting command of inert gas N is generated from a command device 80, the inert gas N flows into both reaction gas sections of a cell 10 to substitute with the reaction gas, while gradually expelling the reaction gas. And a trap 22 within the source of inert gas starts to function, and thus the gas N which does not contain moisture will pass through a sampling chamber 31, and the monitoring of quality for the gas N is started by a moisture meter 32 etc. And after the approximately total amount of the gas N within the cell is substituted with the inert gas N, the moisture in the gas N to be supplied is restrained under 0.1wt%, preferably under 100ppm. Whereby, it is possible to prevent the deterioration of cell performance. |
