研究了由H2S气体,(CoS-Mo2S) /BaCe0.475Zr0.475Y0.05O3-δ/Ag,空气构成的质子传导型固体氧化物燃料电池的制备和电性能,以及在常压、温度范围为600~800 ℃时,温度和燃料气流量对H2S脱除率的影响. 结果表明,H2S脱除率与电流密度之间呈线性关系;电池电流密度和H2S脱除率均随温度的升高而增大,电池适宜工作温度范围为700~800 ℃;在30~80 mL/min范围内,H2S脱除率随燃料气流量增加而增大;在反应温度为800 ℃、燃料气流量为80 mL/min的条件下,电池开路电压为0.72 V,最大电流密度为2.9×10-2 A/cm2,H2S脱除率可达71%.
