description Provided is an air recycling device for a proton exchange membrane fuel cell, wherein a capacity of an air compressor is reduced by resupplying reacted air to a stack of a fuel cell. In a proton exchange membrane fuel cell, electromotive force is obtained by subjecting a fuel gas and an oxidizing gas to an electrochemical reaction via a polymer electrolyte membrane. The air recycling device for a proton exchange membrane fuel cell comprises: a compressor(110) for compressing an oxidizing gas; a humidifier(120) for controlling humidity of the compressed oxidizing gas; a condenser(140) for condensing the oxidizing gas discharged from a fuel cell(130) connected to the humidifier(120); a sensor(150) for checking humidity and pressure of the oxidizing gas discharged from the fuel cell(130); a bypass part(160) for resupplying the oxidizing gas discharged from the fuel cell(130) to an inlet part of the fuel cell(130); a control valve(170) that is provided in the bypass part(160) and interrupts a flow of the oxidizing gas; and a control part(180) that receives signals from the sensors(150) and controls opening and closing of the control valve(170).
