Abstract

Polymer electrolyte fuel cells (PEFCs) are attractive energy resources in transportation and portable applications due to their low operational temperatures, excellent energy densities, and simplicity of storage. For the past decade, metal oxides (MO) have been identified as plentiful supplies with excellent electrochemical properties, low cost, an abundance of hydroxyl groups, and environmentally acceptable alternative to currently available materials. Their intriguing properties such as extremely large surface area, low synthesis cost, and so on, make them ideals for many applications. This review covered MO structure, characteristics, and current preparation methods. MO/metal nanoparticles and MO/carbon nanoparticles are also addressed as electrocatalysts, co-catalysts, or supports, especially in PEMFC and DMFC applications. This review also examined the effects of different MO nanoparticles in polymer and biopolymer membranes on membrane characteristics. Finally, the existing issues and future perspectives of MO nanoparticles are also discussed in this review. GRAPHICAL ABSTRACT

金属氧化物基材料作为燃料电池系统的新兴平台:综述

聚合物电解质燃料电池(PEFCs)由于其低工作温度、优异的能量密度和简单的存储，在运输和便携式应用中具有吸引力。在过去的十年中，金属氧化物(MO)已被确定为具有优异的电化学性能、低成本、丰富的羟基和环境可接受的现有材料的替代品。它们有趣的特性，如极大的表面积，低合成成本，等等，使它们成为许多应用的理想选择。本文综述了MO的结构、特点和目前的制备方法。MO/金属纳米颗粒和MO/碳纳米颗粒也被用作电催化剂、助催化剂或载体，特别是在PEMFC和DMFC应用中。本文还研究了不同MO纳米颗粒在聚合物和生物聚合物膜中的应用对膜特性的影响。最后，对纳米氧化钼存在的问题和未来的发展前景进行了讨论。图形抽象
