Abstract：With the rapid economic development,the problems of environmental pollution and energy shortage have become increasingly prominent,and the development of new energy has been an inevitable trend to achieve sustainable development.From the perspective of development needs,this paper proposes a methanol fuel cell control system based on a microcontroller,mainly composed of fuel cell stack system,control system,auxiliary system and mechanical system.Based on the working principle of direct methanol fuel cell(DMFC)reactor and the research basis of evaluating monomer voltage consistency,the optimal operating parameters of the system are determined by graphical method.Further,the system development is carried out at two levels:overall design and detailed design.Firstly,based on the overall design scheme,the paper elaborates on the analysis of the control system circuit,hardware circuit design,and software program design with the STM32 microcontroller as the core.The research results show that the system operates stably and reliably.Secondly,using Solidworks software,a 3D model of the DMFC casing is created,and ANSYS Workbench is utilized to establish a DMFC simulation model for simulation analysis.Combining 3D printing technology verifies the rationality of the overall design parameters and the alignment of the final product with the initial design intent.Finally,under constant current operation conditions for 90 minutes,the fuel cell system verifies the correctness,rationality,and feasibility of the system design.To provide reference for the research and development of fuel cell energy equipment related to the future new energy industry.
