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 (including 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 that 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 These requirements may be superseded by other standards for equipment containing fuel cell modules as required for particular applications.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 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 appropriate end-product safety requirements. This standard covers only up to the d.c. output of the fuel cell module. This standard does not apply to peripheral devices. This standard does not cover the storage and delivery of fuel and oxidant to the fuel cell module. 1 Also known as proton exchange membrane fuel cell.
