<P>PROBLEM TO BE SOLVED: To provide an operation stop method of a full cell system capable of suppressing fuel cell deterioration as much as possible with a simple and compact configuration. <P>SOLUTION: An operation stop method of a fuel cell system 10 comprises: a first step of making a fuel cell stack 12 generate power while supplying a hydrogen gas and air to the fuel cell stack 12; and a second step of stopping the supply of the hydrogen gas when detecting a stop command of the fuel cell stack 12, and making the fuel cell stack 12 generate power while supplying the air to the fuel cell stack 12. When a fuel gas pressure reaches a lower limit setting value based on an anode-side pressure actually measured in advance, the power generation of the fuel cell is stopped in the second step. <P>COPYRIGHT: (C)2012,JPO&INPIT |
