掺氢天然气SOFC发电系统性能优化研究
Research on performance optimization of hydrogen-doped natural gas SOFC power generation system
摘要
Abstract
This study establishes a model of a solid oxide fuel cell(SOFC)power generation system fueled by hydrogen-enriched natural gas using Cycle-Tempo software.It provides a detailed analysis of the impacts of key operating conditions—such as single-cell voltage and operating temperature—and critical parameters—including hydrogen blending ratio and anode fuel utilization—on the performance of the SOFC system.The results indicate that increasing the hydrogen blending ratio,inlet temperature,single-cell voltage,and anode fuel utilization can enhance power generation.Notably,a higher hydrogen blending ratio significantly reduces greenhouse gas emissions,particularly CO2.Under the conditions of a gas flow rate of 0.0437 kg/s,single-cell voltage of 0.75 V,fuel utilization rate of 80%,fuel cell inlet temperature of 700℃,and hydrogen blending ratio of 60%,the system achieves a power output of 1 220.33 kW with an efficiency of 52.67%,while reducing carbon emissions by 27.86%.关键词
