ABSTRACT:
A gas-supplying apparatus for a fuel cell, which generates electric power due to an electrochemical reaction between oxygen and hydrogen, during which water is produced, and which has respective gas passages within the duel cell according to the present invention comprises a gas-sucking means which supplies supply gas of the fuel cell provided on the downstream of the gas passage in a gas-flowing direction; and a pressure controller which controls the pressure of the supply gas within the fuel cell, provided on the upstream of the gas passage, whereby the water produced during the course of said electrochemical reaction is discharged. When the cell voltage is decreased, the apparatus of the present invention recovers the cell voltage by making the negative pressure large to accelerate the discharge of the produced water with minimized power consumption.
