Proton Exchange Membrane Fuel Cell (PEMFC) are emerging as the new renewable energy source. The output voltage of PEMFC is not sufficient to fulfill the load demands which varies with variations in temperature and load. So, it is integrated with a properly designed power conditioning unit to enhance and stabilize the voltage. In this paper Nexa 1.2 KW PEMFC is initially modeled using successive trust region. Next, a DC-DC boost converter connected to the fuel cell is designed using interval analysis to boost and regulate the output voltage adhering to the changes in the temperature and loading conditions. To stabilize the output of PEMFC fed boost converter, double loop robust controllers are implemented which are designed by Coefficient Diagram Method (CDM). All the responses of the CDM controlled boost converter settle down smoothly at the desired settling time with zero overshoot. The proposed controller fair quite well as compared to other similar controllers in the existing literatures.

质子交换膜燃料电池（PEMFC）逐渐成为新的可再生能源。PEMFC的输出电压不足以满足负载需求，负载需求随温度和负载的变化而变化。因此，它与适当设计的功率调节单元集成在一起，以增强和稳定电压。在本文中，最初使用连续信任区域对Nexa 1.2 KW PEMFC进行建模。接下来，使用间隔分析设计连接到燃料电池的DC-DC升压转换器，以升压和调节粘附在温度和负载条件变化下的输出电压。为了稳定PEMFC馈电升压转换器的输出，实现了采用系数图方法（CDM）设计的双环路鲁棒控制器。CDM控制的升压转换器的所有响应均在所需的建立时间处平稳下降，且过冲为零。与现有文献中的其他类似控制器相比，所提出的控制器还算不错。
