针对一种塔式太阳能光热耦合固体氧化物电解池(SOEC)制氢系统
引入熔盐储热
建立各子系统热力学模型
研究关键操作参数与工作模式对SOEC制氢性能的影响及其对系统电、热功率供需、储热容量与效率的影响。结果表明:相对于热中性模式
SOEC工作在放热模式的电解效率和系统制氢效率都会有所提升
且会减少系统对太阳辐射功率和储热容量的需求
工作温度越低电解效率和系统制氢效率的提升幅度越大。在工作温度为600 ℃的条件下
SOEC工作在进出口温差为100~400 ℃的放热模式时
系统制氢效率可提升5.14%~14.49%。因此
对于与太阳能光热耦合的SOEC系统
SOEC在低工作温度时
适当升高电流密度使其工作在放热模式对于提升自身电解效率和系统制氢效率都具有一定意义。
For a solar thermal power tower coupled solid oxide electrolysis cell (SOEC) hydrogen production system with molten salt thermal storage
the thermodynamic model of each subsystem is established to analyze the effects of key operating parameters and operating modes on the performance of SOEC hydrogen production and its impact on the system electrical power and heat flow rate supply and demand
thermal storage capacity and efficiency. The results show that SOEC operating in exothermic mode enhances both electrolysis efficiency and system hydrogen production efficiency compared with thermo-neutral mode
and reduces solar radiant power and heat storage capacity required by the system. The lower the operating temperature of the electrolysis cell
the greater the enhancement. At the operating temperature of 600 ℃
the hydrogen production efficiency of the system can be enhanced by 5.14 % to 14.49 % when the SOEC is operated in the exothermic mode where the temperature difference between the inlet and outlet is from 100 ℃to 400 ℃. Therefore
for the SOEC hydrogen production system coupled with solar thermal
appropriately increasing the current density at low operating temperatures to make the electrolysis cell work in exothermic mode is of significance to improve both the electrolysis efficiency and the system hydrogen production efficiency.
