Abstract This paper describes the proton exchange membrane fuel cell electric vehicles, the need for engine test bed. Comprehensive analysis of the fuel cell electric vehicle drive system bench main content. Finally, a brief description of the fuel cell power drive system test bed the main structure and function. More than a century the development of automobile industry has made great contributions to mankind, the impact of cars on the far-reaching social progress. However, with a significant increase in the number of vehicles, dell inspiron 1300 battery vehicle exhaust on the human environment harm people gradually understood and valued. To achieve the sustainable development of auto industry, people have been exploring the development of a pollution-free, low noise, easy maintenance and easy manipulation of the advantages of electric vehicles. Since the eighties, many industrialized countries, relevant institutions and auto manufacturers have invested heavily in the development of various types of electric vehicles. Of these, secondary battery electric vehicles, hybrid electric (power) and fuel-cell electric vehicles, electric vehicles and so on. In recent years, proton exchange membrane fuel cell technology, a breakthrough was made, in particular the high specific power and features without charge, make it as a power source for electric vehicle applications, competitive, showing a good prospect. Proton exchange membrane fuel cell is based on hydrogen as fuel and air (O2) as the oxidant to work. In the fuel supply, control of operating conditions and other aspects of the secondary battery different. Therefore, in order to fuel cells as power source for electric vehicle development process, the proton exchange membrane fuel cell Hp nc6000 battery power drive system test method must give special consideration. The author based on testing standards and test automotive engine specifications, and combined experience developing mobile power PEMFC, engine assembly of PEMFC electric car bench problems discussed. the fuel cell drive systems need to bench test , Fuel cell power drive system bench test the necessity and the particularity. Based automotive engine test specifications, development of a new or redesigned vehicles in the road before the examination should be conducted two comprehensive tests: first, the engine before loading the "engine (assembly) bench test"; s Second, after loading the engine "vehicle test bed." No matter what kind of power source of vehicles, "vehicle bench" can be found in Universal's "chassis dynamometer" (also known as: drum dynamometer) on. Car engine (assembly) for the purpose of bench is fully tested the performance of the engine characteristics and to assess and forecast, after loading the engine, the vehicle dynamics and whether the indicators meet the design requirements. This is the process of developing an indispensable vehicle very important part. Therefore, the development of electric vehicle drive systems must also be a bench test. For the "engine (assembly) bench test", depending on the type of fuel the engine, operation mode, dell inspiron 5100 battery and the different nature of the measured parameters, to use a different engine test bed. Currently, in addition to GM's automotive engine test stand, the second rechargeable battery electric vehicle drive system also has a dedicated test bed. In view of fuel cell electric vehicles in the hydrogen fuel supply, fuel cell test operations support system and other aspects of special parameters, the proton exchange membrane fuel cell electric vehicles must use a dedicated test bed.
