Fuel cell based heat and power cogeneration is considered to be well qualified for a distributed energy system for residential and small business applications. A fuel processing unit including an oxidative steam methane reformer, a high temperature shift reactor and a low temperature shift reactor is under development in South China University of Technology. Performance of the unit is experimentally investigated in a bench-scale experimental setup. Processor performance under typical operating conditions is tested. The influence of reaction temperature, methane space velocity in the oxidative steam methane reformer, and air to carbon molar ratio on unit performances is experimentally studied. It is found that under the typical operating conditions, the total energy efficiency reaches 88.3 % . The efficiency can further be improved by utilizing the sensible heat of the reformate gas. The current study has been focused on the chemical performances such as methane conversion of the reformer and CO concentration in the synthesis gas downstream water gas shift reactors. Heat integration of the unit will be further implemented in future to improve energy efficiency.
