FUEL CELL SYSTEM

摘要

A fuel cell system is provided to improve a recycling efficiency of water and to omit equipment for treating water by recycling the water generated at an electricity generation part. A fuel cell system(100) comprises an electricity generation part(110) which generates electricity by the electrochemical reaction of hydrogen and oxygen; an oxygen supply part(160) which supplies an oxygen-containing gas to the electricity generation part; a reformer(120) generates the hydrogen gas supplied to the electricity generation part; a fuel tank(130) which supplies the fuel to the reformer; a condensation tank(140) which condenses the water comprising the vapor discharged from the electricity generation part; and a gas-liquid separator(150) which stores the water supplied from the condensation tank to supply it to the reformer, and separates a hydrogen gas from the reformed gas comprising a hydrogen gas and vapor supplied from the reformer to supply it to the electricity generation part.
