Abstract


Become one of the hot research field of new energy technologies because of its high energy efficiency, low noise, zero pollution, design, simple operation, low temperature start, security and stability of the many advantages of proton exchange membrane fuel cell (PEMFC: Proton Exchange Membrane Fuel Cell) . Water and heat management problems of proton exchange membrane fuel cell has a crucial impact on the operating performance of the battery, improper water and heat management will make the output of the battery power is low, the efficiency is very poor, and even affect the life and safety of the operation of the fuel cell proton exchange membrane fuel cell system radiator design for stable play to the performance of the fuel cell has an important significance. This article on the history of the development of the fuel cell, the domestic and international fuel cell commercialization of research and development and application of the status quo and development trend of relatively clear exposition. Elaborated by the introduction of the basic knowledge of the fuel cell, the working principle, the type and characteristics of the fuel cell. In this paper, the basic theory of proton exchange membrane fuel cell electrochemical reaction, including PEMFC works, composed of the structure, performance influencing factors, thus contributing to the in-depth understanding of the fuel cell electrode reaction process, calculation of the electrochemical reaction energy conversion efficiency, the heat generated, and the like. The fuel cell electrode reaction of the chemical through the hydrogen and oxygen is directly converted into electrical energy, and the electrochemical reaction generates heat and water. Thermal management of the fuel cell, battery internal fluid flow and heat transfer control to maintain the heat balance and the water balance of the battery. PEMFC stack of the main cooling and power for comparison and selection of the cooling liquid of the heap; this paper on the stack in the heat balance calculation of heat and the heat generated in the stack operation. The working temperature, it must be effectively controlled in order to ensure that the fuel cell stack to work stably. Chapter PEMFC power generation system cooling requirements, this level 5kW fuel cell power generation system radiator material selection and structural design, and with calculating the radiator design verification. And by a further calculation to determine the choice of the fan and the main control strategy to ensure that the work of PEMFC power generation systems when stack temperature in the appropriate range. This article describes the level 5kW fuel cell power generation system, the air supply subsystem, hydrogen supply subsystem, cooling water subsystem, as well as the design of the control system, power generation system has been tested, and the test results were analyzed and summarized Looking further research directions .
