Fuel cell system for electricity generation, has flow channel integration mechanism through which exhaust gas and vapor that enters gas-liquid separation tank is released to external environment by condensation and evaporation device

摘要

A fuel supply pump (190) is located between fuel tank (180) and flow channel integration mechanism (111), so that fuel is supplied from fuel tank to fuel cell stack (140). The exhaust gas produced by reaction of the fuel cell stacks is flowed into fuel tank. The exhaust gas and vapor that enters gas-liquid separation tank (170) through flow channel integration mechanism is released to external environment of fuel cell system by condensation and evaporation device (150). A supply terminal (220) is connected with container (210) and connector portion (221) having fuel delivery conduit (221a) and air line (221b), located in fuel feed line. A one-way valve (230) is connected to the air line, such that air is flowed to container.
