Absstract of: WO2023183749A1

An apparatus, namely an infrared (IR) interference shield, is described that can be utilized with a vehicle that employs hydrogen fueling, such as a fuel cell electric vehicle (FCEV). For example, the IR interference shield is mounted onto the vehicle's hydrogen fueling receptacle. The IR interference shield is distinctly structured to reduce or prevent interference of IR wireless communication between a vehicle-side IR transmitter on the receptacle, and an IR receiver of the hydrogen fueling station. The IR interference shield can block interference to IR signals that may negatively affect IR wireless communication between the hydrogen fueling station and the vehicle. Thus, the IR interference shield improves reliability of the communication between the vehicle and the hydrogen fueling station, thereby improving the overall effectiveness and efficiency of the hydrogen refueling process.
