FUEL CELL SYSTEM

A fuel cell system includes a fuel cell (34), a combustion portion (36), an evaporation portion (32) generating a water vapor by evaporating a supplied reforming water, a reforming portion (33) generating the reformed gas with the water vapor and with a raw material for reformation, a housing (39) containing the evaporation portion (32) and the reforming portion (33), the housing (39) including a bottom portion (39a) that is heated, a perforated plate (32a) being provided within the housing (39), the perforated plate (32a) having a plurality of holes being penetrated therethrough, and a reforming water supply pipe (11b) including a first end and a second end in order for the reforming water discharged from the reforming water pump (11b2) to run down the perforated plate (32a) and to move towards the bottom portion (39a), the second end (11b1) facing and opening to the perforated plate (32a).
