Low Concentration Gas Fuel Reforming Technology and Electrochemical Performance Analysis
This study analyzes the catalytic reforming effect of low concentration gas in solid oxide fuel cells.In the analysis process,the carbon oxygen ratio is studied as the main regulatory variable,and low concentration gas fuel is used as the main catalytic agent.Firstly,a nickel based yttria stabilized zirconia(Ni-YSZ)anode supported half cell was studied as a reforming catalytic reactor,and the catalytic reforming reaction and fuel composition changes under different carbon oxygen ratios were compared and analyzed.Afterwards,the study analyzed the performance changes of low concentration gas solid oxide fuel cells with different carbon oxygen ratios by preparing solid oxide fuel cells.The research results show that as the carbon oxygen ratio continues to decrease,the methane conversion rate shows a trend of increasing at the front end of the change and decreasing at the back end.At the same time,in the electrochemical performance testing of low concentration gas solid oxide batteries,at 750℃,the battery can stably provide a voltage of 0.78 V for a long time,and there is no obvious carbon deposition in the anode during this process,which combines efficiency and stability.
