Abstract
In China, coal is a dominant energy source. In order to ensure China’s energy security, coal should be used efficiently and cleanly. Integrated gasification fuel cell hybrid power generation system is a promising system for coal utilization. It combines clean coal gasification technology with high efficient fuel cell technology. In this work, the performance of solid oxide fuel cell using syngas as fuel was investigated, based on the commercial computational fluid dynamic software and the developed program used to analyze chemical, electrochemical, heat/mass transfer, current, and electric potential. The results show that the temperature difference is about 300 K in the cell under all calculation conditions. Along the cell length, hydrogen concentration rapidly reduces, and its decrement is larger than that of carbon monoxide. The variation of current density in electrolyte layer is relatively small along the direction of gas flow, but it is obvious along the direction vertical to gas flow.
