UL SUBJECT 2265A

Abstract

These requirements cover hand-held or hand-transportable fuel cell power units that use disposable methanol fuel cartridges. These requirements also cover the disposable fuel cartridges. These requirements apply to power units that provide dc outputs rated 60 Vdc or less and 240 VA or less. As such, the internal and external circuitry are considered secondary circuits that are "SELV." <br>The fuel cell power units covered by these requirements are for use in unclassified (ordinary) locations in ambient temperatures that do not exceed 60&#176;C (140&#176;F). The fuel cell power units are to be integrated into information technology equipment on the production line by the original equipment manufacturer. The fuel cartridges are to be installed and replaced by the end-product user. <br>These requirements cover fuel cell power units that are electrical power sources that include integrated electrical connection means, integrated wiring material leads with or without electrical connectors, or a combination of these arrangements for single or multiple electrical loads. Additional electrical connection means may be provided to affect information exchange with the end-use product as designed. <br>These requirements cover disposable fuel cartridges and fuel cell power units that are not intended for use with common consumer electronics appliances. <br>Federal regulatory requirements pertaining to the shipment of fuel cartridges is outside the scope of this Outline of Investigation. <br>This Outline of Investigation establishes requirements for disposable fuel cartridges limited in pressure to the vapor pressure of the methanol fuel. <br>Disposable cartridges with a fuel capacity greater than 950 mL and refillable cartridges are excluded from this Outline of Investigation. <br>The technologies covered by these requirements include direct methanol fuel cell stacks and fuels identified as methanol, or methanol and water mixtures with or without additives.
