为了提高燃料电池装置的供电可靠性,本文基于质子交换膜燃料电池电堆,采用高性能、低成本、低功耗的STM32作为控制芯片,模拟了采样电路,设计了一个嵌入式控制方案。该设计采用结构化方案,分为主控器模块和功能子模块两部分,每个模块之间的通信运用控制器区域网络(controller area network,CAN)总线协议,基于labVIEW的设计应用平台,实现了燃料电池的氧气和氢气供应系统以及风冷系统的控制和监测,并以图形化的方式动态显示燃料电池系统的工作状态。实验结果表明,该控制方案提高了质子交换膜燃料电池的供电可靠性,具有可实现性和良好性。该研究具有一定的应用价值。

In order to improve the reliability of the fuel cell,based on the proton exchange stack,a high performance,low cost and low power consumption STM 32 is used as the control chip,and an embedded control scheme is designed to simulate the design of the sampling circuit.The design of this scheme uses a more structured solution.The design uses a structured program,and the scheme is divided into two main control module and functional sub-module.The communication between each module uses the Based on the labVIEW software design platform,the oxygen supply system of the fuel cell,the hydrogen supply system and the control and monitoring of the air cooling system are realized,and the fuel cell system is dynamically displayed in a graphical way.The experimental results show that the control scheme improves the reliability of the power supply of proton exchange membrane fuel cells,with good feasibility.This research has certain application value.
