<P>PROBLEM TO BE SOLVED: To conduct appropriate purge control in a fuel cell system equipped with a purge valve and a drain valve in an anode circulation system. <P>SOLUTION: When power generation voltage Vf is lowered than a prescribed voltage, a control device 70 opens a purge valve 30 first in the first exhaust, and thereby, fresh reaction gas is supplied to a fuel cell, and when exhaust gas is exhausted by the purge valve 30, since moisture attached to an anode of the fuel cell 14 is exhausted at the same time, the power generation voltage Vf can be recovered in an early stages. <P>COPYRIGHT: (C)2007,JPO&INPIT |
