藉由控制进口气体组成物增强ＳＯＥＣ系统生命周期;ENHANCING SOEC SYSTEM LIFETIME BY CONTROLLING INLET GAS COMPOSITION

摘要

本发明提供一种用于增强固态氧化物电解池系统之生命周期之方法，该方法藉由对抗该系统之串联电加热器之线的氮化作用达成，启动、停机及跳脱操作在增湿氮气氛围中于燃料侧上进行以达成在-70℃与23℃之间的露点，及在空气或在二氧化碳中于氧气侧上进行，从而保证在堆叠中之氧气侧上遍及电池之整个表面始终存在充分氧化条件。 In a method for enhancing the lifetime of a solid oxide electrolysis cell system by counteracting nitridation of the threads of the in-line electrical heaters of the system, the start-up, shut-down and trip operations are done in a humidified nitrogen atmosphere on the fuel side to achieve a dew point between -70℃
