对质子交换膜燃料电池（PEMFC）建立合适的数学模型，有助于改善 PEMFC 的设计。结合燃料电池的电场与温度场，建立了包含质子交换膜燃料电池的电化学模型与温度模型的数学模型，通过MATLAB 软件进行仿真，仿真结果表明该模型较好地反映出 PEMFC 系统的动态特性，并研究了工作温度、反应气体工作压力以及质子交换膜面积变化对电池输出性能的影响。与此同时结合所建立的质子交换膜燃料电池模型设计了一款采用 PID 控制的 Boost 升压电路，将燃料电池输出不稳定的电压转变成可供给负载稳定使用的24V 电压。

Appropriate modelling and simulation system of Proton exchange membrane fuel cell is helpful to impro?ving PEMFC design. In this paper, based on the electric field and temperature field of fuel cells, a mathematical model of a number of proton exchange membrane fuel cells is built, using the temperature and the electrochemical model. Through MATLAB simulation, the results show that the model better reflects the dynamic PEMFC system properties. The changes of operating temperature, gas pressure and membrane area, which affect the performance of the fuel cell output, were studied. At the same time, we designed a boost converter using PID control for proton ex?change membrane fuel cell model, thus converting the fuel cell output voltage into stable supply 24 V for load.
