摘要
文章基于Cycle-Tempo软件建立了掺氢天然气固体氧化物燃料电池(SOFC)发电系统模型,并详细分析了燃料电池的单电池电压、反应温度等工作条件和掺氢量、阳极燃料利用率等关键参数对SOFC发电系统的影响。研究结果表明:提高掺氢比、进口温度、单电池电压和阳极燃料利用率可以提高发电量,掺氢比提高可显著降低温室气体尤其是CO_(2)的排放;当燃气流量为0.0437kg/s、单电池电压为0.75V、燃料利用率为80%,燃料电池进口温度为700℃、掺氢比为60%时,发电量为1220.33kW,效率为52.67%,碳排放量降低27.86%。
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 CO_(2).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 C,and hydrogen blending ratio of 60%,the system achieves a power output of 1220.33 kW with an efficiency of 52.67%,while reducing carbon emissions by 27.86%.
