  • 本研究針對中溫質子傳導型固態氧化物燃料電池複合系統分析。根據理論利用Matlab計算出燃料電池之性能曲線,並應用於商用軟體Thermolib進行系統模擬。文中建立四種不同燃料電池複合系統,各系統之系統配置有些許不同,並且在相同操作條件下進行比較,操作條件為燃料當量比1.4 ~ 1.7、空氣當量比2 ~ 4。


    In this research, the performance of intermediate-temperature proton-conducting solid oxide fuel cell hybrid systems is investigated. It is analyzed by using Matlab/Simulink/Thermolib. There are four different fuel cell hybrid systems. The configuration of each system is slightly different, but is analyzed under the same operating conditions. Flow rates of hydrogen and air are controlled by assigning different stoichiometric ratio, which are 1.4 - 1.7 and 2 - 4 respectively.
