摘要

在正在进行的能源供应转型中，氢是一种很有前途的能源载体，但通过电解槽生产氢的成本仍然过高。为了解决这一挑战，本文提出了一个先进的面向方程的PEM（聚合物-电解质-膜）电解系统过程模型，包括电解槽和下游氢压缩，旨在优化其操作参数（即电流密度、温度、压力）的相互作用。首先，该模型通过操作流程优化来分析电解系统的孤立性能，然后将其集成到更广泛的能源系统中进行操作规划优化。

Optimizing temperature and pressure in PEM electrolyzers: A model-based approach to enhanced efficiency in integrated energy systems

Hydrogen stands as a promising energy carrier within the ongoing energy supply transformation, yet its production via electrolyzers remains prohibitively costly. To address this challenge, this paper proposes an advanced equation-oriented process model for a PEM (Polymer-Electrolyte-Membrane) electrolysis system, including the electrolyzer and downstream hydrogen compression, aimed at optimizing the interaction of its operating parameters (i.e., current density, temperature, pressure). Initially, the model is utilized to analyze the isolated performance of the electrolysis system through operational flowsheet optimizations, followed by its integration into a broader energy system for operational planning optimization.
