Introduction
?€?Proton exchange membrane fuel cell - General technical specification of fuel cell stacks?€? is one of the series national standards developed basing on the important technical standard research project ?€?Research on Key Technical Standards of New Energy and Renewable Energy - Proton Exchange Membrane Fuel Cell, Solar Hot Water System, Grid-Connected Photovoltaic Power Generation and Wind Turbine?€? of the national ?€?Tenth Five-Year Plan?€? major science and technology special projects, combining with China?€?s ?€?863?€? plan fuel cell electric vehicle major project proton exchange membrane fuel cell technology. This Part specifies the basic requirements for the safety and performance, and requirements for type inspection and routine inspection items, test methods, and marking and documentation of proton exchange membrane fuel cell stacks (including direct methanol fuel cell stacks). This Part applies to proton exchange membrane fuel cell stacks (including direct methanol fuel cell stacks).
Fuel cells are not only suitable for the construction of stationary power plants to provide community and household power supply, more importantly, on-board fuel cells can provide power supply for electric vehicles and micro-fuel cells are used in a variety of communications equipment, laptops and handheld computers. The fuel cell technology is transformed from the research and development in these aspects to industrialization, and commercialization of fuel cells in stationary power plants, transportation power supply, portable power supply, etc. is coming. Technologies associated with fuel cells will also be commercialized in the next 5 to 10 years. Some new technologies, new materials and new components will also be developed rapidly on the basis of internationalization of the market, and it is expected that fuel cell technologies will be developed continuous at high speed.
In ?€?Ninth Five-Year Plan?€? and ?€?Tenth Five-Year Plan?€? periods, China has taken proton exchange membrane fuel cells (PEMFC) and related technologies as a major project and included it in the national scientific and technological research, including ?€?863?€? fuel cell vehicle major project plan, and has achieved the staged results. At present, China?€?s PEMFC technologies are technically supported by universities and research institutes, and leaded by several major high-tech enterprises, and the research bases in Dalian, Shanghai, Beijing and Wuhan have been established. Some of them have acquired patented technology with independent intellectual property rights, and are actively promoting the industrialization and commercialization of China?€?s fuel cell technologies.
Early development of standards is very important for promoting the industrialization and commercialization of this new technology with unlimited development potential - fuel cells. International Electrotechnical Commission (IEC) has set up IEC/TC 105 to be responsible for the standard developing of fuel cells. In recent years, it works frequently, which has issued the very first fuel cell international standards IEC 62282- Proton exchange membrane fuel cell -
