Abstract


The fuel cell is the fourth generation of thermal power, hydropower and nuclear power generation after generation technology, it is a highly efficient, clean power generation, distributed generation system has broad application prospects. Fuel cell control system is the core of the entire system is safe, reliable, efficient operation, and has now achieved the core IPC semi-automated control system because of the bulky, high cost limited the development of the fuel cell power generation system, while traditional complex control tasks difficult to complete the 8-bit microcontroller, can not reach the control requirements of the system. Embedded technology-based proton exchange membrane fuel cell system is designed as a standby power grid voltage appears abnormal, intelligent and fuel cell miniaturization. The main object of study of this paper is the proton exchange membrane fuel cell (Proton Exchange Membrane Fuel Cell, PEMFC) In addition to the general characteristics of the fuel cell, and also has a fast start at room temperature, non-polluting, zero emission, easy to discharge water, life long, high energy conversion efficiency salient features. Therefore, it has become the most extensively studied in the field of fuel cell today, one of the fastest growing branch, has been widely used in military applications, mobile devices, households, stationary power plants. This paper describes the composition and working principle of the system and its water, heat, electricity, gas management and control, design a set of 5kW fuel cell power generation system. Introduced the basic content of the embedded system on the overall design of the control system. The main content of the paper is the design and implementation of hardware systems; software design and implementation of embedded Linux environment; to stack temperature subsystem mathematical modeling and simulation. The major work done in this article: 1. Built a 5kW proton exchange membrane fuel cell system. The core of the control system of the fuel cell is based on the ARM9 core S3C2410 microprocessor, embedded Linux system for the operating system. At the same time, build a master module, driver module, interaction module hardware system. 2. Achieve a cross-compiler environment, Linux2.6 kernel transplantation, the establishment of a development environment for embedded systems. Software system, application software, according to the control requirements of the fuel cell power generation system, modular design, multi-process combined with the method of multi-threaded Linux environment to achieve real-time control loop of the fuel cell power generation system, and complete system operation monitoring interface design. 3 a temperature control based on fuzzy PID control algorithm. Stack temperature control of fuzzy PID control algorithm based on the analysis of characteristics of the fuel cell stack model simulation using matlab be seen from the simulation results of the algorithm to improve the performance of the system.
