HT-PEFC Systems Operating with Diesel and Kerosene for APU Application

Fuel cell — Battery hybrid systems for auxiliary power units

“…The reaction heat is recovered in an integrated heat exchanger to evaporate water for the reformer. Experimental results and experiences with the hightemperature polymer electrolyte fuel cell system with diesel reforming have been published in [4][5][6].…”

Recent advances in diesel autothermal reformer design

“…Fuel cell systems operated on renewable H2 can be applied to vehicle propulsion itself, whereas fuel cell systems using reforming processes for H2 generation from liquid carbonaceous energy carriers are suitable for auxiliary power units (APUs) for on-board power supply in aircraft or trucks (i.e., for air conditioning, heating, cabin systems, etc.). Samsun et al [2] explain that fuel cell-based APUs with diesel reforming can achieve an efficiency of 40%, which is the efficiency target of the U.S. Department of Energy [3,4]. One of the most important and complex components of such an APU is the reforming unit for generating H2 from liquid carbonaceous feedstocks, for which autothermal reforming (ATR), heated steam reforming (HSR) and partial oxidation (POX) are the most common processes.…”

A survey of nickel-based catalysts and monolithic reformers of the onboard fuel reforming system for fuel cell APU applications

“…The theoretical net efficiency of an integrated reformer and fuel cell APU system can be in the range of 25–40% , whereas the efficiency of a conventional gas turbine APU is only 11–15% . The elevated hydrocarbon fuel utilization efficiency can effectively mitigate the fuel depletion risk.…”
