For marine applications auxiliary power units (APU) that are based on a reformer/fuel cell systems instead of a conventional motor/generator have several advantages. Namely low emissions and low noise generation become increasingly important, especially when ships are docked in the harbor. Since the power trains of ships are fuelled by marine diesel, this hydrocarbon will also be the fuel for their APU systems. This paper describes the development of an autothermal diesel reformer at Fraunhofer ISE, Germany. After successful start-up the reformer pilot plant was operated for 300 hours, with only slight catalyst degradation. Soot formation was not observed, and trace amounts of higher hydrocarbons only (less than 20 ppm) were found in the reformer product gas.The design of the 350 kWel technology demonstrator plant is currently well underway. This plant will consist of a HDS unit for on-board desulfurization of marine diesel, an ATR reformer based on the pilot plant developed by Fraunhofer ISE and a MCFC by Ansaldo Fuel Cell. Operation of the integrated plant is scheduled to start in 2005.
