Fuel Cell Modules for Use in Portable and Stationary Equipment
   

Scope

1 These requirements cover component fuel cell modules for building into equipment, including portable and stationary fuel cell applications.

2. These requirements also cover proton exchange membrane (PEM), alkaline, phosphoric acid, molten carbonate, solid oxide type fuel cell modules that are intended to be factory installed in complete products.

3. These requirements do not cover removable fuel cartridges for refueling the fuel cell module.

 

This is the second issue of the Outline of Investigation for Fuel Cell Modules for Use in Portable and Stationary Equipment. Note that the first issue of the outline was named Portable Proton Exchange Membrane (PEM) Type Fuel Cell Power Plants With Or Without Uninterruptable Power Supply (UPS) Features And Portable Proton Exchange Membrane (PEM) Type Fuel Cell Modules For Factory Installation In Original Equipment Manufacturer (OEM) Type Equipment For Indoor Use

UL Subject 2262A
Borohydride Fuel Cartridges with Integral Fuel Processing for Use with Portable Fuel Cell Power Systems or Similar Equipment
   

Scope

1. These requirements cover disposable borohydride compound fuel cartridges with integral fuel processing for use with portable fuel cell power systems or similar equipment that use gaseous hydrogen from the cartridge. The fuel contained within the cartridge consists of a sodium or potassium borohydride formulation, or a mixture of these formulations, which have been shown to be UN Class 8 (Corrosive) materials. The compounds, in liquid state are processed through a chemical reaction within the cartridge that results in hydrogen gas (for use as a fuel) and borate solution (waste material stored in the cartridge until disposal).

2. These requirements also cover cartridges that contain fuel consisting of UN Class 4, Division 4.3 (Water Reactive) borohydride compounds. The compounds, in solid state, are processed with the addition of water resulting in a chemical process that results in hydrogen gas (for use as fuel) and borate solution (waste material stored in the cartridge until disposal).

3. These requirements cover cartridges for use in portable fuel cells systems, but do not cover cartridges for use in equipment intended to be brought on board passenger aircraft.

4. The fuel cell cartridges covered by these requirements are for use in ambient temperatures that do not exceed 50C (121F) and whose internal pressures do not exceed 100 psig.

5. Federal regulatory requirements pertaining to the shipment of fuel cartridges are outside the scope of this Outline of Investigation.
