Fundamental Structural Studies of Polymers in Fuel Cell/Green Hydrogen Applications

庄信万丰（JM）在氢技术方面投入了大量资金，例如在燃料电池和绿色氢领域。该项目旨在为燃料电池和绿色氢配方中使用的关键聚合物、溶剂和活性颗粒之间的复杂相互作用提供基本的理解。典型的配方可以由活性贵金属支撑的碳和/或金属氧化物颗粒，在导电聚合物（聚电解质）存在下的溶剂类型（水性和非水性）以及非离子型组成。聚合物还表现出流变改性特性，在结合聚合物的情况下，当它们吸附到颗粒表面时，充当结构剂。推进对聚合物在这些体系中的行为及其与其他配方组分的相互作用的基本理解，对于下一代配方的成功开发至关重要，并直接适用于涂层工艺和燃料电池等应用的性能。

Johnson-Matthey (JM) has invested heavily in Hydrogen Technologies e.g., in the area of Fuel Cellsand Green Hydrogen. This project will aim to provide fundamental understanding of the complexinteractions between critical polymers, solvent and active particles that are used in fuel cells and greenhydrogen formulations. A typical formulation can be composed of active precious metal supportedcarbon and/or metal oxide particles, solvent-types (aqueous and non-aqueous) in the presence ofconducting polymers (polyelectrolytes), as well as non-ionic types. Polymers also exhibit rheologymodifying properties and, in the case of associative polymers, act as structuring agents when theyadsorb onto the particle surface. Advancing the fundamental understanding of polymer behaviour insuch systems and their interactions with the other formulation components is expected to be criticalfor the successful development of next-generation formulations and directly applicable to coatingprocesses and the performance of the application e.g., fuel cell.
