【摘要】：氫氧燃料電池,顧名思義,是在催化劑的作用下,陽極的氫氣和陰極的氧化劑進(jìn)行反應(yīng),釋放電和熱,同時(shí)生成液態(tài)或氣態(tài)形式的水。相比原電池及原油,對(duì)環(huán)境的污染更少,是一種綠色、清潔和高效的可循環(huán)利用的新型能源。因此,在化石燃料日趨減少及能源危機(jī)的今天,具有非常好的開發(fā)及應(yīng)用前景。 根據(jù)其電解質(zhì)的不同,有5種不用類型的氫氧燃料電池,其中質(zhì)子交換膜燃料電池(PEMFC)能夠在室溫下快速啟動(dòng),并具有可反復(fù)開關(guān)和低噪音等特性,在便攜式電源、交通工具以及基站電源等領(lǐng)域具有很好的應(yīng)用前景。然而,需要良好的水熱管理策略和健壯的軟件控制,才能使PEMFC燃料電池系統(tǒng)的效率盡可能地發(fā)揮,保證燃料電池系統(tǒng)長時(shí)間正常地運(yùn)行。本文在對(duì)PEMFC電池的工作性質(zhì)和各模塊的參數(shù)進(jìn)行了理論結(jié)合實(shí)際的分析和權(quán)衡之后,提出了一個(gè)簡單實(shí)用、適用于固定基站的燃料電池的水熱氣管理策略,主要工作如下： (1)對(duì)燃料電池的歷史、主流氫氧燃料電池的主要結(jié)構(gòu)和工作原理做了簡要的回顧和學(xué)習(xí)。 (2)對(duì)PEMFC電池性能參數(shù)的進(jìn)行了分析,并闡述水熱氣管理的重要地位。 (3)設(shè)計(jì)了燃料電池控制系統(tǒng),以STM32F103微處理器為核心,搭建硬件電路；以IAR公司的EWARM作為軟件開發(fā)平臺(tái),并在IAR平臺(tái)上移植FreeRTOS實(shí)時(shí)系統(tǒng)；對(duì)燃料電池的溫度、電流、電壓和氫氣壓力進(jìn)行采集及分析。 (4)實(shí)現(xiàn)了數(shù)字PID對(duì)燃料電池的溫度控制,通過實(shí)驗(yàn)繪制出最佳的燃料電池電流—溫度曲線,以達(dá)到最佳的發(fā)電效率；對(duì)于增濕策略及氣管理方案,設(shè)計(jì)了安秒短路和排氣的方法；同時(shí)在軟件方面實(shí)現(xiàn)了對(duì)燃料電池系統(tǒng)的智能化控制,能夠在系統(tǒng)出現(xiàn)錯(cuò)誤的情況下保護(hù)系統(tǒng)。 (5)設(shè)計(jì)了LabVIEW上位機(jī)程序,主要用于接收STM32F103通過串口發(fā)送的燃料電池的參數(shù),并作數(shù)據(jù)顯示、保存,以便分析燃料電池的性能。 經(jīng)試驗(yàn)測(cè)試表明,該系統(tǒng)運(yùn)行穩(wěn)定,在模擬系統(tǒng)出錯(cuò)的情況下,能夠迅速做出響應(yīng)以保護(hù)系統(tǒng),對(duì)氫氧燃料電池領(lǐng)域的研究和推廣具有一定的參考價(jià)值。
[Abstract]:Hydrogen-oxygen fuel cell, as its name implies, is a reaction between anode hydrogen and cathode oxidant under the action of catalyst, which releases electricity and heat, and produces water in liquid or gaseous form at the same time. Less pollution than primary batteries and crude oil, it is a green, clean and efficient renewable energy source. Therefore, fossil fuels are becoming less and energy crisis today, which has a very good prospect of development and application. Depending on their electrolytes, there are five types of hydrogen and oxygen fuel cells, among which the proton exchange membrane fuel cell (PEMFC) can be quickly started at room temperature, with features such as repeatable switching and low noise, in portable power supply. Vehicle and base station power supply and other fields have a good application prospects. However, good water and heat management strategy and robust software control are needed in order to maximize the efficiency of PEMFC fuel cell system and ensure the fuel cell system to run normally for a long time. After analyzing and weighing the working properties of PEMFC battery and the parameters of each module, a simple and practical hydrothermal gas management strategy for fixed base station fuel cell is put forward in this paper. The main work is as follows: (1) A brief review and study on the history of fuel cell, the main structure and working principle of the mainstream hydrogen oxygen fuel cell is given. (2) the performance parameters of PEMFC battery are analyzed, and the important position of hydrothermal gas management is expounded. (3) Design fuel cell control system, take STM32F103 microprocessor as the core, build hardware circuit, take EWARM of IAR company as software development platform, and transplant FreeRTOS real-time system on IAR platform. Voltage and hydrogen pressure are collected and analyzed. (4) realize the temperature control of fuel cell by digital PID, draw the best current-temperature curve of fuel cell through experiment, and achieve the best power generation efficiency. The method of short circuit and exhaust is designed, and the intelligent control of fuel cell system is realized in software, which can protect the system if there are errors in the system. (5) the program of LabVIEW host computer is designed, which is mainly used to receive the parameters of fuel cell sent by STM32F103 through serial port, and to display and save the data so as to analyze the performance of fuel cell. The test results show that the system runs stably and can respond quickly to protect the system when the simulation system goes wrong. It has certain reference value for the research and popularization of hydrogen oxygen fuel cell field.
