The present invention relates to an air control valve for a fuel cell vehicle, comprising: a valve housing in which an air flow path is formed; a first valve member selectively opening and closing the air flow path; a first sealing member arranged in the first valve member, and sealing between the air flow path and the first valve member; a second valve member disposed to be spaced apart from the first valve member and selectively opening and closing the air flow path; a second sealing member arranged in the second valve member and sealing between the air flow path and the second valve member; and a driving unit driving the first valve member and the second valve member such that the first valve member and the second valve member move from a first position for blocking the air flow path to a second position for opening the air flow path, thereby improving airtight performance and suppressing deterioration of a fuel cell stack.
