Abstract
A fuel cell system includes a fuel cell stack, a gas liquid separator, a first drain channel, and a second drain channel. The gas liquid separator is connected to a fuel gas discharge passage of the fuel cell stack through a fuel gas discharge channel. The first drain channel is connected to the fuel gas discharge passage separately from the fuel gas discharge channel, and connected to the gas liquid separator through a valve unit. The second drain channel chiefly discharges liquid droplets from the gas liquid separator.
