FUEL CELL SYSTEM AND STARTING METHOD THEREOF

摘要

A fuel cell system is provided to start a stack quickly without bad effect in the dehydration state of a membrane within the fuel cell stack. A fuel cell system(10) comprises a fuel cell stack(20) and a starting control part(30) controlling output voltage at both ends during starting to the starting voltage lower than the rated voltage. An initial driving method of the fuel system comprises the steps of: (a) step for starting the fuel cell stack by supplying the fuel; and (b) controlling output voltage at both ends during starting to the starting voltage lower than the rated voltage.
