Abstract
A fuel cell system is provided, which includes a fuel cell configured to generate power by a reaction of fuel as and air, an air compressor configured to compress air and supplying the compressed air to the fuel cell, a controller configured to control operations of the fuel cell and the air compressor, and an exhaust system member configured to discharge off-gas and produced water from the fuel cell. When a first condition including a flow rate of air by the air compressor being greater than a first flow rate is satisfied, the controller increases a rotational speed of the air compressor to supply air at or more than a second flow rate that is greater than the first flow rate to the fuel cell, and to discharge water inside the fuel cell.

A fuel cell system, comprising:
- a fuel cell configured to generate power by a reaction of fuel gas and air;
- an air compressor configured to supply air to the fuel cell;
- a controller configured to control operations of the fuel cell and the air compressor;
- and
- an exhaust system member configured to discharge off-gas and produced water from the fuel cell,
- wherein when a first condition including a flow rate of air supplied to the fuel cell by the air compressor being greater than a first flow rate is satisfied, the controller increases a rotational speed of the air compressor to supply air at or more than a second flow rate that is greater than the first flow rate to the fuel cell, and to discharge water inside the fuel cell.
