中文摘要:
      质子交换膜燃料电池PEMFC(proton exchange membrane fuel cell)水管理不当会增加内阻阻碍氧还原反应,因此有效的水管理是提高性能和耐久性的关键策略之一。膜脱水、催化剂层溢流、质量传输和流体流动状态等现象会受到流道中水的分布和移动的影响。对PEMFC水管理的关键技术相关文献进行了综述,讨论了改善水管理的各种技术方案,汇总了采用中子成像和电子显微镜等技术对液滴的形成、扩散以及与气体扩散层GDL(gas diffusion layer)的相互作用进行研究的成果。详细分析了采用CFD模型和VOF方法模拟燃料电池微通道中的水滴运动和段塞形成。
英文摘要:
      The poor water management of a proton exchange membrane fuel cell(PEMFC) will increase its internal resistance and hinder the oxygen reduction reaction. Therefore, effective water management is one of the key strategies to improve its performance and durability. It is also worth noting that the phenomena including membrane dehydration, catalyst layer overflow, mass transfer and fluid flow state will be affected by the distribution and movement of water in the passage. In this paper, the related literature on the key technologies of PEMFC water management is reviewed, and various technical solutions to the improvement of water management are discussed. Moreover, the research results of the formation and diffusion of liquid droplets and their interaction with gas diffusion layer(GDL), which are studied using tec-hniques such as neutron imaging and electron microscopy, are summarized. The simulations of the movement of water dro-plets and slug formation in fuel cell micro-channels using the CFD model and VOF method are also analyzed in detail.
