Abstract

Typically, polymeric materials experience material degradation and damage over time in harsh environments. Improved understanding of the physical and chemical processes associated with possible damage modes intended in high-pressure hydrogen gas exposed atmospheres will help to select and develop materials well suited for applications fulfilling future energy demands in hydrogen as an energy carrier. In high-pressure hydrogen gas exposure conditions, damage from rapid gas decompression (RGD) and from aging in elastomeric as well as thermoplastic material components is unavoidable. This review discusses the applications of polymeric materials in a multi-material approach in the realization of the “Hydrogen economy”. It covers the limitations of existing polymeric components, the current knowledge on polymeric material testing and characterization, and the latest developments. Some improvements are suggested in terms of material development and testing procedures to fill in the gaps in existing knowledge in the literature.

摘要

通常，聚合物材料在恶劣环境中会随着时间的推移而发生材料降解和损坏。更好地理解与高压氢气暴露环境中可能的损伤模式相关的物理和化学过程，将有助于选择和开发非常适合应用的材料，以满足未来氢作为能源载体的能源需求。在高压氢气暴露条件下，快速气体减压 (RGD) 以及弹性体和热塑性材料组件的老化是不可避免的。本综述讨论了聚合物材料在多材料方法中在实现“氢经济”中的应用。它涵盖了现有聚合物成分的局限性，目前关于聚合物材料测试和表征的知识，以及最新进展。在材料开发和测试程序方面提出了一些改进，以填补文献中现有知识的空白。
