Abstract

The invention provides a fuel cell system to be mounted on a vehicle. The system includes a fuel cell configured to generate electric power through chemical reaction of reactive gases, a gas-liquid separator configured to separate water from an off-gas discharged from the fuel cell and store the separated water, a discharge valve configured to drain the water flowing out through an opening at a bottom of the gas-liquid separator, an attitude control device configured to control an attitude of the gas-liquid separator relative to the vehicle, and an instruction device configured to send an instruction for a control target of the attitude of the gas-liquid separator to the attitude control device.

Description

technical field [0001] The present invention relates to fuel cell systems. Background technique [0002] The gas-liquid separator separates and stores liquid water from the anode off-gas discharged from the fuel cell (for example, JP-A-2008-262735 and JP-A-2009-87858). An opening is provided at the bottom of the gas-liquid separator, and the opening is connected to a discharge valve through a discharge pipe. When the discharge valve is opened, the liquid water accumulated in the gas-liquid separator is discharged. [0003] However, the liquid water in the gas-liquid separator does not always accumulate in a place suitable for drainage. For example, in a fuel cell system mounted on a fuel cell vehicle, when the fuel cell vehicle accelerates, the liquid water in the gas-liquid separator is deflected to the opposite side of the acceleration direction, so it may be difficult to discharge the liquid water away from the opening. In addition, when the fuel cell vehicle is parked...
