Optimisation of Operational Parameters Based on Simulation Numerical Model of Hydrogen Fuel Cell Stack Used for Electric Car Drive

摘要

Hydrogen fuel cell stack is used as a rare and sophisticated power source in nowadays electric cars. Our team has built ultra-light energy-efficient vehicle for research purposes that uses hydrogen fuel cell stack as a power source and electric engines as sole drive of the car. The problem of optimizing the operating parameters of the hydrogen fuel cell stack was solved by numerical simulation studies conducted on a simulation model of the hydrogen fuel cell stack. The paper presents a numerical simulation model of hydrogen fuel cell stack system developed in Matlab Simulink and the results of simulation allow the selection and optimization of the control parameters adapted to the specific conditions of use. The model reflects the performance characteristics of the cell and allows the simulation work and control of hydrogen fuel cell stacks composed of hydrogen tank, control valves and controller, sensors, energy buffer system (supercondensers) etc. The model of electric power source based on hydrogen fuel cell stack was built as a module that can be used in the previously developed simulation models of electric vehicles.
