  • Fuel cell system including a separation membrane
    Patent number: 11710837
    Abstract: A fuel cell system including: a first fuel cell performing power generation using a fuel gas; a separation membrane separating at least one of carbon dioxide or water vapor from an anode off gas discharged from the first fuel cell; a second fuel cell disposed in the downstream of the separation membrane and performing power generation using the anode off gas, the anode off gas having at least one of carbon dioxide or water vapor separated therefrom; and a distribution channel disposed on a permeation side of the separation membrane and distributing any of the following: a raw material gas serving as the fuel gas to be reformed and used for the power generation of the first fuel cell, a cathode gas including oxygen to be used for the power generation of the first fuel cell, an anode off gas discharged from the second fuel cell, a cathode off gas discharged from the first fuel cell and to be supplied to the second fuel cell, or a cathode off gas discharged from the second fuel cell, in which at least one of per
