Mathematical modelling of hydrogen transportation from reservoir tank to hydrogen fuel cell electric vehicle (FCEV) tank

Abstract

Mathematical modeling of Hydrogen transfer from reservoir tank to fuel tank of vehicle can help to transfer hydrogen fuel in safe and efficient way. Hydrogen refueling model using MATLAB version 22 has developed in this work. This simulated model can accurately estimate the cooling power required to ensure target hydrogen temperature at destination tank. This model tested for both perfect hydrogen and semi perfect hydrogen for cooling power estimation. The outcomes such as cooling power (KW), pressure (bar), gas density (kg/cm3) and temperature (K) measured using this model at different cooling temperatures −5 °C, −25 °C, −45 °C, −65 °C and the outcomes were compared. From the simulation results it is found that minimum cooling power of 5.431 KW required for hydrogen transfer from reservoir tank to vehicle tank when cooling temperature maintained at −5 °C. The proposed model also provides optimum pressure of 580 bar, temperature of 270 K and gas density of 45.12 kg/cm3.Thus, this model can provide insight into hydrogen transfer in safe and efficient manner.
