  "textContent": "A system and a method for sensing hydrogen charge state of a fuel cell electric vehicle are provided. The system includes an infrared transmission unit that transmits a fuel door sensing infrared signal for sensing a fuel door opened while charging hydrogen and a nozzle sensing infrared signal for sensing a charging station-side hydrogen charging nozzle connected to a hydrogen charging inlet of a vehicle. An infrared reception unit receives the fuel door sensing infrared signal and thereafter, reflected on a fuel door and the nozzle sensing infrared signal transmitted from the infrared transmission unit and thereafter, reflected on the hydrogen charging nozzle. A controller determines that the vehicle is being charged with hydrogen when sensing an open state of the fuel door and a hydrogen charging inlet connection state of the hydrogen charging nozzle.",
