摘要

水的管理是PEM燃料电池技术中需要克服的一个关键问题。模型在燃料电池的发展中起着重要的作用,因为它们能够理解不同参数对电池性能的影响,从而可以系统地模拟、设计和优化燃料电池系统。在这项工作中,一个先前开发和验证的模型被用来预测水通过细胞的运输。研究了膜的厚度和输运性能、反应物压力、相对湿度和操作温度对膜中水分含量和电池性能的影响。该模型预测了膜电极组件(MEA)上的膜含水量和水浓度分布。这项工作是一个有用的工具,可以建立合适的操作条件,从而优化水管理,从而提高PEM燃料电池的性能。

Water management in PEMFC: 1-D model simulations

The water management is a critical problem to overcome in the PEM fuel cell technology. Models play an important role in fuel cell development since they enable the understanding of the influence of different parameters on the cell performance allowing a systematic simulation, design and optimization of fuel cells systems. In this work, a model previously developed and validated, is used to predict the water transport through the cell. The influence of membrane thickness and transport properties, reactants pressure and relative humidity and operation temperature, on the water content through the membrane and on the cell performance was studied. The model predicts the membrane water content and water concentration profiles across the membrane electrode assembly (MEA). This work represents a useful tool to set-up suitable operating conditions leading to an optimised water management producing a better performance for PEM fuel cells.
