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-

This section applies to proton exchange membrane fuel cell stack. This section relates only harmful to human and environmental hazards fuel cell external circumstances, and internal damage to the fuel cell stack protection, they do not affect the safety of the fuel cell stack in addition, this section is not specified. This section does not include the storage of fuel and oxidant and a fuel and oxidant and the conveying device transport process. If there is a better material or new structures, but also through this part of the required inspection and meet the relevant requirements, can also be considered to comply with this section. |
