  • Publication number: 20080206611
    Abstract: A fuel cell system includes a fuel cell (10), a supply passage (11) through which fuel gas and oxidizing gas are supplied to the fuel cell, an exhaust passage (12) through which the fuel gas and the oxidizing gas are discharged from the fuel cell, and a reactor (13) provided in the exhaust passage (12) such that a fuel off-gas from the fuel cell is oxidized. The fuel cell system further includes a bypass passage (14) that extends from the supply passage (11) to reach the reactor (13) and returns to the supply passage (11) such that at least a portion of the fuel gas and the oxidizing gas supplied to the fuel cell upon activation thereof is supplied to the bypass passage 14 and heated in the reactor (13). The bypass passage (14) is communicated with an inside of the reactor (13) such that the gas is heated and humidified under a reaction in the reactor (13) upon activation of the fuel cell.

  • Publication number: 20060263658
    Abstract: A fuel cell system which reduces a quantity of hydrogen in hydrogen off-gas discharged from a fuel cell, and then discharges the hydrogen off-gas to atmosphere, includes an adjusting valve that suppresses a pulsed change in a flow quantity of hydrogen off-gas, which is intermittently discharged from the fuel cell to an exhaust passage and therefore flows in the exhaust passage in a pulse manner, such that the flow quantity becomes constant (stable).
