Despite the numerous experimental reports on MOF-doped PEMs, their increased proton conductivity is commonly ascribed to enhanced water uptake. The underlying mechanisms from a microscopic perspective remain elusive. Therefore, this work explores the microstructure and water diffusion dynamics within composite membranes to decipher their mechanisms involved in proton conductivity using molecular dynamics (MD) simulations. Four types of composite membranes based on two representative MOFs i.e. UiO-66 and UiO-66-NH₂ and two PEMs including Nafion and Dow, respectively, were taken into account. It is revealed that the UiO-66-NH₂ doped Nafion composite membrane exhibits the highest water uptake among the four composite membranes resulting from the super hydrophilicity of UiO-66-NH₂. Besides, the more concentrated distribution of sulfonic groups near the water-PEM interface and the higher interface roughness of UiO-66-NH₂ doped Nafion lead to more water molecules surrounding its sulfonic groups that are favorable for the proton dissociation from sulfonic groups. Furthermore, the increased water channel connectivity of MOF-doped membranes that promotes proton transport through water via the Grotthuss mechanism demonstrates one of the mechanisms for increased proton conductivity. On the other hand, although the reduced lifetime of the hydrogen bond network and the enhanced water diffusion coefficient within MOF-doped membranes manifest the favorable proton transfer via the Vehicle mechanism. Overall, UiO-66-NH₂ doped Nafion membranes exhibiting the highest water channel connectivity and water diffusion coefficients demonstrate the greatest potential of UiO-66-NH₂ doping in advancing the proton conductivity. These findings provided microscopic insights into understanding the improved proton conductivity mechanism of MOF doped PEMs, and the approaches developed in this work may be extended to other composite membranes.</div></div>","PeriodicalId":337,"journal":{"name":"International Journal of Hydrogen Energy","volume":"97 ","pages":"Pages 236-246"},"PeriodicalIF":8.1,"publicationDate":"2024-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142747324","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper aims to present a comprehensive overview of hydrogen preparation strategies, recent advances in storage and transportation technologies, and the extensive application of hydrogen in many fields. First, we explored the current mainstream hydrogen preparation paths, including but not limited to hydroelectrolysis (decomposition of water molecules using renewable energy power); gas steam reforming (traditional but efficient hydrogen production methods requiring carbon emission management); biomass gasification and coal gasification (based on innovative utilisation of renewable and fossil resources); and hydrolysis hydrogen production (advanced cutting-edge technology directly using solar energy). Each method shows its unique advantages and potential application scenarios. Subsequently, we have focused on hydrogen storage technology, a key area that is undergoing rapid technological innovation and widespread application. Hydrogen storage technology, with its energy storage and release characteristics without carbon dioxide emissions, is regarded as an important bridge to promote the transformation of energy structure and achieve the sustainable development goals. This paper not only expounds the basic principle of hydrogen storage technology and historical evolution, also analyzed in detail in the compressed hydrogen, liquid hydrogen and solid hydrogen storage form of concrete application examples, at the same time, the selection of hydrogen storage materials, cost efficiency, safety performance and deeply analyzes the core challenges, and the future development trend and potential solutions. In terms of hydrogen transport, this paper will introduce three common transport modes: gas transport, liquid transport and hydrogen carrier transport. Further, we turned to the diversified utilisation technology of hydrogen, focusing on the breakthroughs of fuel cell technology in energy conversion efficiency, Hydrogen combustionand, thow hydrogen energy can help to achieve low-carbon travel in the transportation field. The integration and application of these technologies not only broaden the use of hydrogen energy, but also lay a solid foundation for them to occupy a core position in the clean energy system. To sum up, through a detailed review, this paper draws a panorama of hydrogen production, storage, transportation and use, revealing the key role and huge potential of hydrogen energy in the clean energy transition.
