Simulation of Fuel Cell Power Generation System Based on AMESim

Abstract

Fuel cell has become the main power source of the fuel cell electric vehicle due to its advantages of high ideal energy conversion efficiency, low noise, high reliability and maintainability. The fuel cell power generation system is an integrated system including the fuel cell stack. Its physical model covers many subjects such as electricity, thermodynamics, hydrodynamics and electrochemistry, which makes it difficult to change the simulation of fuel cell power generation system. In order to study the characteristics of fuel cell system, the model of proton exchange membrane fuel cell system is set up using AMESim. The model mainly includes fuel cell stack, gas supply subsystem, cooling subsystem and DC/DC converter. On this basis, the characteristics of fuel cell stack and its subsystems under dynamic conditions are analyzed.
