【摘要】：為研究基于LSCF-GDC氧電極的固體氧化物電解池堆的電解性能,自制了30單元(10 cm×10 cm)的平板式電解電堆,通過改變固體氧化物電解池堆的操作溫度、水蒸氣含量、氣體流量等條件,記錄不同條件下電解的極化曲線。分析操作條件對高溫電解水蒸氣極化的影響,并計(jì)算電解制氫的系統(tǒng)效率。結(jié)果表明較高的溫度、水蒸氣含量、水蒸氣流量,以及氧電極空氣的通入有利于降低過電位;在800℃,通入6 L×min~(-1) 90%濕度的氫氣,電解電壓為1.27 V時(shí),系統(tǒng)效率達(dá)到最大值80.8%,此時(shí)電堆的產(chǎn)氫速率為4.57 L×min~(-1)。
[Abstract]:In order to study the electrolysis performance of solid oxide electrolytic reactor based on LSCF-GDC oxygen electrode, a 30 unit (10 cm 脳 10 cm) flat type electrolysis reactor was made. The operating temperature, water vapor content and gas flow rate of the reactor were changed. The polarization curves of electrolysis were recorded under different conditions. The effect of operation conditions on the water vapor polarization of high temperature electrolysis is analyzed, and the system efficiency of hydrogen production by electrolysis is calculated. The results show that high temperature, water vapor content, water vapor flow rate and oxygen electrode air flow can decrease the overpotential, and at 800 鈩，
