Abstract
A method for removing residual water in a fuel cell stack includes: blocking, by an air compressor, air supply to a fuel cell stack upon shutting down of fuel cell; measuring a cell voltage of the fuel cell stack while the air supply is blocked; estimating an amount of residual water in the fuel cell stack based on the measured cell voltage of the fuel cell stack; and removing, by a driving controller, the residual water in the fuel cell stack by driving the air compressor based on the estimated amount of water.
