摘要

摘要: 建立了质子交换膜燃料电池阴极的传质模型,综合考虑了影响电堆传热的多个因素,在此基础上针对内增湿式燃料电池堆建立了动态传热模型.采用Runge-Kutta-Felhberg法对模型进行求解,对电流、反应物过量系数、压强、冷却水流量等对电堆温度的影响进行了研究.结果表明,当电流大于25A时电堆温度将不能自行稳定在80℃以下,采用水冷可以有效地将电堆温度控制在较理想的范围内.在额定功率为5kW的燃料电池堆试验台架上进行了热管理试验,试验结果同模型预测值吻合较好.

Abstract: A transient heat transfer model of proton exchange membrane fuel cell (PEMFC) stack with internal humidification,based on mass transportation phenomena in cathode,was developed. Factors affecting the stack temperature were considered. Equations were solved with Runge-Kutta-Felhberg method. Results indicate that the stack temperature can-t be maintained below 80℃ itself when current exceed 25A. Influence of current,pressure,stoichiometric ration and water flow rate on stack temperature were researched as well. Heat management tests were carried out on a 5kW PEMFC stack,and a good agreement was found between tests and model prediction.
