Hydrogen, and specifically green hydrogen can play a key role in decarbonisation, as it has the potential to be used as fuel for power and transportation. Water electrolysis, and in particular solid oxide electrolysis, is attractive due to its high energy efficiency. There are challenges related to the performance, lifetime, durability and cost of solid oxide electrolysers, along with their scale-up from kW to MW level. The interconnect plays an important role with in the electrolyser stack as a current collector and a physical barrier that separates the electrodes between cells. It has to meet strict technical requirements within the harsh operating environment of the solid oxide electrolyser. One of the challenges with using steel interconnects is the evaporation of chromium from the interconnect, leading to chromium poisoning of the air electrode and degradation of the electrolyser performance. This project aims to address this issue and to enhance the durability of solid oxide electrolyser stacks by using PVD-coated interconnects and metal-ion infiltrated electrodes.

氢，特别是绿色氢，可以在脱碳中发挥关键作用，因为它有潜力用作电力和交通燃料。水电解，特别是固体氧化物电解，由于其高能源效率而具有吸引力。固体氧化物电解槽的性能、寿命、耐用性和成本以及从千瓦级扩展到兆瓦级的规模都存在挑战。互连件在电解槽堆栈中发挥着重要作用，作为集电器和分隔电池之间电极的物理屏障。它必须满足固体氧化物电解槽恶劣运行环境下严格的技术要求。使用钢互连件的挑战之一是铬从互连件蒸发，导致空气电极铬中毒和电解槽性能下降。该项目旨在解决这一问题，并通过使用 PVD ​​涂层互连和金属离子渗透电极来提高固体氧化物电解槽堆栈的耐用性。
