Abstract
At the optimum filling the hydrogen into the Fuel Cell Electric Vehicle (FCEV) tank along the standard protocols, one of the important factors is the inlet temperature of the hydrogen. Therefore, it is important to measure the temperature of the inlet hydrogen correctly at the hydrogen station. However, no one indicates that how much error level is included on the temperature measured in the hydrogen refueling station. In this paper, the error of temperature measurement in the hydrogen refueling station is clarified and the calibration equations of the measured temperature are proposed.
