<p><P>PROBLEM TO BE SOLVED: To provide a fuel cell system preventing an output from being unstable due to sudden change of methanol concentration to enable to stably operate the fuel cell system (DMFC (Direct Methanol Fuel Cell)). <P>SOLUTION: The DMFC system is provided with: a stack carrying out electricity production reaction using methanol and oxygen; a separator housing gas-liquid mixture exhausted from the stack and separating into gas and liquid; a methanol cartridge with high-concentrated methanol stored; and a fuel mixing portion including a housing space separated from the separator, mixing the high-concentrated methanol supplied from the methanol cartridge and liquid supplied from the separator in the housing space, and diluting into low-concentration methanol to be supplied to the stack. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
