A method of discharging water from a mobile object, which includes a fuel cell, a gas-liquid separator, and a circulation pump, comprises: an inclined state detection step of detecting an inclined state of the mobile object with respect to a horizontal plane; a scavenging start step of starting to supply scavenging gas at a predetermined first supply flow rate to a gas flow path in the fuel cell, by driving the circulation pump; and a supply flow rate increase step of increasing, when the mobile object is in a predetermined inclined state in which an outlet of the gas flow path is directed upward against a direction of gravity, a rotational speed of the circulation pump so that the supply flow rate of the scavenging gas is increased to a second supply flow rate higher than the first supply flow rate after a predetermined period from starting to supply the scavenging gas.
