Due to the depletion of fossil fuels and environmental issues such as atmosphere pollution, fuel cell power generation system with high efficiency and low emission is being pursued. Traditionally, pre-reforming system, such as steam reforming, has been used in almost every fuel cell system to produce hydrogen as the fuel. We studied the use of homogeneous charge compression ignition engine as an external reformer for the fuel cell system, whose operation occurs in an excessively rich condition leading to un-catalyzed in-cylinder partial oxidation. An exergy analysis was performed to compare HCCI reforming system with steam reforming one. From the results, it was shown that the fuel-air mixture was not fully reformed in HCCI reforming system, because the exhaust stream is not in the equilibrium state, while we should operate it at O/C > 0.8. The efficiency and power output of HCCI reforming system showed that the efficiency of HCCI reforming system is greater due to the heat balance of each system, although the power output of HCCI reforming system is relatively small as compared to that in steam reforming system.
