空冷自增湿质子交换膜燃料电池发电控制器设计

摘要

为便于对空冷自增湿质子交换膜燃料电池(PEMFC)发电进行控制,根据空冷自增湿PEMFC的控制特性设计一种基于STM32F103微控制器的嵌入式发电控制器.该控制器通过采集PEMFC电堆的温度、输出电流、输出电压等参数,按照设计的控制策略,实时输出相应控制信号控制电堆稳定运行.通过实验验证了该发电控制器运行可靠、监控性能良好、实用性强,为空冷自增湿型PEMFC的实时发电控制提供了一种嵌入式控制方式.%According to the characteristics of proton exchange membrane fuel cell (PEMFC), a general controller based on STM32F103 is designed to control the electricity generation of PEMFC in this paper. In accordance with the designed control strategy, the controller can output real-time control signals to control the stable PEMFC operation by sampling the parameters such as temperature, output current and output voltage, etc. With experimental verification, it turns out that the controller has reliable operation and good monitoring performance, which provides an embedded control method for electricity generation of the PEMFC.
