<P>PROBLEM TO BE SOLVED: To provide a fuel cell system which can identify the region where shortage of hydrogen or air is occurring in the fuel cell, and which can remove impurities only from the region where the shortage of the hydrogen or the air is occurring. <P>SOLUTION: Local currents at locations in divided regions A to C of the fuel cell 10 where the shortage of the fuel gas is easy to occur are measured by a plurality of local current measuring means 20 to 22, and among the respective divided regions A to C of the fuel cell 10, the fuel gas in the divided regions A to C where the local current measured by the local current measuring means 20 to 22 is less than a prescribed value of the local current is exhausted by a fuel gas exhausting means 43a to 43c. Local currents at the locations in the divided regions A to C of the fuel cell 10 where the shortage of the oxidizer gas is easy to occur are measured by a plurality of local current measuring means 20 to 22, and among the respective divided regions A to C of the fuel cell 10, the oxidizer gas in the divided regions A to C where the local current measured by the local current measuring means 20 to 22 is less than a prescribed value of the local current is exhausted by oxidizer gas exhausting means 33a to 33c. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
