  "textContent": "A device for controlling compensation for an air flow rate upon discharge of hydrogen off-gas and a method for controlling compensation for an air flow rate using the same is an air flow rate control device configured to control a flow rate of air supplied to a fuel cell cathode through an air supply unit of a fuel cell system, wherein the air flow rate control device is configured to determine whether a fuel discharge valve of the fuel cell system is opened and determine a fuel diffusion amount per unit time, wherein the fuel diffusion amount corresponds to an amount of the hydrogen off-gas discharged through the fuel discharge valve and diffused into an air supply unit through a humidifier, and compensate a target air flow rate depending on an oxygen concentration reduction proportion, determined according to the determined fuel diffusion amount per unit time and flow rate information of the air supply unit.",
