Modeling and Simulation of Vehicle-mounted Methanol Reforming Hydrogen Fuel Cell Power Generation System

Fuel cells can convert chemical energy stored in fuel into electric energy efficiently and environmentally friendly, and hydrogen is the best fuel for fuel cells. At present, large companies related to automobiles and energy in developed countries are accelerating the development of fuel cells. Using on-board methanol reforming to produce hydrogen is one of the solutions to the problems existing in hydrogen production, transportation, distribution and hydrogenation of fuel cell vehicles. In this paper, based on the modeling idea of combining mechanism with experience, a complete fuel cell model using methanol reforming to produce hydrogen is built. After the simulation test, the simulation results show that the output speed of the motor varies with the working conditions, and the speed of the motor is small under the urban cycle working conditions, but the driving scene is complex, and there are many acceleration and deceleration situations. Compared with the urban working conditions, the speed of the vehicle is large under the high-speed working conditions, and there is usually no sudden acceleration or deceleration. Integrating hydrogen production with fuel cell, and making hydrogen raw materials easily available and transported, can solve the current promotion problem of pure hydrogen fuel cell. At present, methanol reforming hydrogen production technology can solve the problem of on-board hydrogen production.
