Abstract:Current proton exchange membrane fuel cell technology has been rapid development in the United States, Canada, Japan and Germany in developing the kinds of batteries for power source has been an upsurge of research. Fuel cells fuel efficiency of its unique high quality high energy, high power, long power, long life, high reliability, low noise, and does not produce harmful emissions caused by NO2, etc is the world's attention. Many countries and research entities have the proton exchange membrane fuel cell (PEMFC) application study on the expansion to the automotive market, mainly for passenger  cars  and  family  cars  manned  the  power  source  to  solve  environmental problems. 2012, the U.S. market with fuel cell-powered cars will reach 60 million (total U.S. vehicle market share of about 4%), which uses proton exchange membrane fuel cell (PEMFC) power plant as fuel cell vehicles will account for about 80% of total number of vehicles. PEMFC has been recognized as the best car of the future power source.

　　　This topic comes from fuel-cell vehicle development project, which aims to energy shortages in today's social context of pressure to achieve a fuel cell vehicle based on PEMFC vehicle development, and explore fuel cells eventually replace the internal combustion  engine  vehicles  effective  way. Research  project  based  on  project  needs, design a set of laboratory tests kW PEMFC system and the system of the PEMFC based on a detailed performance testing, performance optimization for the automotive PEMFC provided strong support.

　　　This paper briefly describes the historical development of PEMFC and the present status and the basic working principle of PEMFC, outlined the development of laboratory testing  of  kW  PEMFC  system,  the  composition  and  working  principle  and  system software development platform - the history of virtual machines and application situation, the paper focuses on the core issues of content - based on LabVIEW for data acquisition programming. Subjects  completed  the  test  system  acquisition  program  is  modular, compact, real strong, extensible, and so the characteristics of the stack's performance evaluation, activation, operating conditions and optimize software performance laid the foundation-line monitoring.
