35、82-2:201262282-2 IEC:2012 7 FUEL CELL TECHNOLOGIES Part 2: Fuel cell modules 1 Scope This part of IEC 62282 provides the minimum requirements for safety and performance of fuel cell modules and applies to fuel cell modules with the following electrolyte chemistry: alkaline; polymer electrolyte (incl

36、uding direct methanol fuel cells)1; phosphoric acid; molten carbonate; solid oxide; aqueous solution of salts. Fuel cell modules can be provided with or without an enclosure and can be operated at significant pressurization levels or close to ambient pressure. This standard deals with conditions tha

37、t can yield hazards to persons and cause damage outside the fuel cell modules. Protection against damage inside the fuel cell modules is not addressed in this standard, provided it does not lead to hazards outside the module. These requirements may be superseded by other standards for equipment cont

38、aining fuel cell modules as required for particular applications. This standard does not cover road vehicle applications. This standard is not intended to limit or inhibit technological advancement. An appliance employing materials or having forms of construction differing from those detailed in the

39、 requirements of this standard may be examined and tested according to the purpose of these requirements and, if found to be substantially equivalent, may be considered to comply with this standard. The fuel cell modules are components of final products. These products require evaluation to appropri
