A transforming society towards sustainable industrial practices and products chooses to implement “Green Nanomaterial”, with high energy efficiency, minimizing the damage to the environment and exploitation of non-renewable energy resources. A combined overview of recent developments in green nanostructured fuel cells with enhanced durability and activity is presented in this review along with the advancements of green nano materials in the area of corrosion inhibition.

Fuel cells being the next generation ecofriendly energy source, the modification to the solid oxide, microbial and alkaline fuel cell through green nanomaterial are discussed with an emphasis on electrodes, electrolyte, electrode catalysts and membrane components. In addition, the role of green nanomaterial in the form of nano metal oxides, hydroxides, grains, dendrimers, gels, composites, functionalized graphene, halloysite nanotubes and ionic liquids in greening the phenomenon of corrosion inhibition, investigated by various researchers is briefly addressed.

As no single engineered green nanomaterial is emerging as unparalleled and most viable, they are evaluated according to their economic impact, diverse properties, durability and stability. Eventually, these materials with improvement in biocompatibility, solubility, fabrication and handling techniques are predicted to change the environmental and occupational scenario, with some of them already have been found to impact upon the altering global energy needs.

一个向可持续工业实践和产品转型的社会选择实施“绿色纳米材料”，具有高能效，最大限度地减少对环境的破坏和不可再生能源的开发。本综述综合概述了具有增强耐用性和活性的绿色纳米结构燃料电池的最新发展以及绿色纳米材料在腐蚀抑制领域的进步。

燃料电池是下一代环保能源，讨论了通过绿色纳米材料对固体氧化物、微生物和碱性燃料电池的改性，重点讨论了电极、电解质、电极催化剂和膜组件。此外，绿色纳米材料以纳米金属氧化物、氢氧化物、晶粒、树枝状大分子、凝胶、复合材料、功能化石墨烯、埃洛石纳米管和离子液体的形式在绿化腐蚀抑制现象中的作用，由不同的研究人员进行了简要介绍。

由于没有单一的工程绿色纳米材料成为无与伦比和最可行的，因此根据其经济影响、多样化的特性、耐用性和稳定性对其进行评估。最终，预计这些在生物相容性、溶解性、制造和处理技术方面有所改进的材料将改变环境和职业场景，其中一些已经被发现会影响不断变化的全球能源需求。
