摘要

有机-无机纳米复合膜的应用允许无机材料的理想热学和机械性能与聚合物材料的反应性、介电性能、耐久性、柔韧性和可加工性之间的协同作用。质子交换膜燃料电池(pemfc)存在一些问题,包括水含量管理、一氧化碳中毒、氢重整和燃料通过膜的交叉。本文针对上述问题提出了有机-无机纳米复合材料的具体解决方案。这些解决方案包括在质子交换膜中掺杂质子导电无机纳米粒子、溶胶-凝胶法制备纳米复合材料、无机化合物与聚合物结构的共价键、酸基质子交换纳米复合膜。此外,还对乙醇蒸汽重整法低一氧化碳制氢以及CO在PEMFC进料中的作用进行了解释和讨论。最后,讨论了在交换膜细胞(emfc)中实现最大功率密度的理想条件。

Proton Exchange Membrane Fuel Cells: Focused on Organic-Inorganic Nanocomposite Membranes
The application of organic-inorganic nanocomposite membranes allows for a synergy between the desirable thermal and mechanical properties of inorganic materials with the reactivity, dielectric properties, durability, flexibility, and processability of the polymeric materials. Proton exchange membrane fuel cells (PEMFCs) suffer from some problems including water content management, carbon monoxide poisoning, hydrogen reformate, and fuel crossover through the membrane. Herein, specific solutions have been proposed to the above-mentioned problems using organ-inorganic nanocomposites. These solutions include doping proton conductive inorganic nano-particles in the proton exchange membrane, preparing nanocomposites via the sol-gel method, covalence bond of inorganic compounds with the polymer structure, and acid-based proton exchange nanocomposite membranes. Furthermore, hydrogen production with low carbon monoxide content using the ethanol steam reforming method, as well as the effect of CO in the hydrogen feed of PEMFC are explained and discussed. Finally, desirable conditions for achieving the maximum power density in exchange membrane cells (EMFCs) are discussed.

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
