Abstract
The determining step in PEFC Polymer Electrolyte Fuel Cell) systems for power generation is the develoment of a flexible (fossil hydrocarbons) processor to provide hydrogen or hydrogen rich reformate gas. A low cost and efficient fuel processing system represents the transition bridge to the future commercialization of this technology for stationary applications. This papaer covers the activities performed at CNR-ITAE Institute aimed at developing a pre- commercial hydrogen generator unit, named HYGenII, (now under assembling) for residential applications and a niche markets, in a power range up to 5 kWe. The prototype, based on our first HYGen ! (2kWe) system, successfully realized and tested, can convert light hydrocarbons (methane, propane, LPG, butane) in a hydrogen rich mixture. Authothermal reforming and intermediate temperature water gas shift processes coupled with a PSA (Pressure Swing Adsorption) unit take to obtain hydrogen with a purity of 99.999%. The expected efficiencies, ATR and prototype, (calculated as hydrogen higher heating value on propane higher heating value) reach about 59 and 71%, respecively.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
