这项工作致力于热力学解释和电气网络分析的电解槽电池（EC）系统组成的低/高温电解槽和热机的操作考虑。详细的电流密度，所需的功率，和实践热的轨迹已被解决，以证明在制氢速率和效率，以及功耗方面的系统的最佳操作模式。合适的模拟在热添加和热移除（在热添加之后发生）之间的热中性（TN）模式下呈现边界电流路径。结果表明，高温电解槽与来自太阳能或地热的可再生能源的集成以优化制氢效率并降低功耗具有很高的意义。更重要的是要理解，在恒温下，除热可以进一步提高热中性路径上的产氢速率。分析还表明，增加可再生热量和最小化面积比电阻（ASR）将是非常可取的，以进一步发展高效和低消耗的EC系统。
This work is devoted to thermodynamic interpretations and electrical network analyses for the operational considerations of electrolyser cell (EC) systems composed of low/high-temperature electrolysers and heat engines. Detailed trajectories of current density, required power, and practice heat have been addressed to demonstrate the optimal operation mode of the systems in terms of hydrogen production rate and efficiency, as well as power consumption. Suitable simulations exhibit a boundary current path at the thermal neutral (TN) modes between heat addition and heat removal (occurring after heat addition). Results indicate that the integration of high-temperature electrolysers with renewable energy from solar or geothermal to optimize the hydrogen production efficiency and reduce power consumption is of high interest. It is more important to understand that heat removal can further increase hydrogen production rate over thermoneutral path at constant temperature. The analyses also demonstrates that adding renewable heat and minimizing area specific resistance (ASR) would be highly desirable for further developing high-efficient and low-consumption EC systems.
