BS EN 62282-2:2004 Fuel cell technologies. Fuel cell modules

Fuel cell modules are components of final products. These products require evaluation to appropriate end-product safety requirements. Fuel cell modules are electrochemical devices which convert continuously supplied fuel, such as hydrogen or hydrogen rich gases, alcohols, hydrocarbons, and oxidants to d.c. power, heat, water and other by-products.

BS EN 62282-2 provides the minimum requirements for safety and performance of fuel cell modules. It applies to fuel cell modules with the following electrolyte chemistry:

– Alkaline

– Proton exchange membrane (including direct methanol fuel cells)

– Phosphoric acid

– Molten carbonate

– Solid oxide fuel cell modules.

Fuel cell modules might be provided either with or without an enclosure and might be operated at significant pressurization levels or close to ambient pressure.

BS EN 62282-2 deals with conditions that can harm people and damage outside the fuel cell modules only. Protection against damage to the fuel cell modules itself is not addressed in this standard, unless it leads to hazards outside the module.

BS EN 62282-2 does not apply to road vehicle applications. It also does not limit or inhibit technological advancement.
