Abstract
It is important for the fuel cell integrated movable system to operate voltage and current using safety control technology. In order to work at the convenient condition of the fuel cell system, high performance fuel cell stack with replaceable fiber bipolar plate should be arranged with the integrated subsystem and appropriate working process. The parameters which affect the performance of PEMFC consisting of relative humidity, reaction temperature, gas inlet temperature, gas inlet pressure, and hydrogen and air flow rate. This study is to develop the integrated movable system on distributed power generation and backup power application, such as oxidant supply system, fuel supply system, heat management system, water management system, and power conditioning system. It comprises a novel PLC (Programmable Logic Control) system and human-machine interface. The controller is developed to control fuel cell system and record the operation data by using data acquisition system. The controller can be applied to high performance stack and system to obtain the best performance. The easy-taken high capacity hydrogen barrel embedded into steel plate of this movable system and more convenient than other fuel cell system.

Summary
Many researchers have discussed the importance and the need for well designed control system for fuel cell power supply. From the discussions with control engineers and researchers in the area of fuel cell technology, it became apparent that a comprehensive development with a control-oriented approach to modeling, analysis, design, and cost down was needed. Important properties that affect the performance of PEM fuel cells include transport of reactants and byproducts, rejection of the heat generated by electrochemical reactions or by the current passing through the fuel cell and control of fuel cell stack, hydrogen fueling, reaction temperature, air supply, cooling, PLC controller, power conversion, and data acquisition to maintain adequate electrolyte conductivity [1]. The proton exchange membrane fuel cell group is required by the conditions of the target
