New Routes to Large Surface Area Sinters for Rapid Response Electrolysers

PEM电解槽电池的活性面积影响电流消耗、氢气产生和电负载能力。目前可以实现的最大电池面积仅由金属烧结部件的当前可用性决定。利用更大面积的电解槽电池具有显著的优点，包括更大的氢气产生能力以及降低的集成和控制要求，从而实现更具成本效益的解决方案和更大的电负载封装在更小的系统中。该项目将研究新型烧结钛结构，用作大型（> 1000平方厘米）导电液体扩散层，用于快速响应，高性能聚合物电解质膜水电解槽，用于生产清洁燃料和能源储存的氢气。大型烧结矿的性能评估将为ITM下一代高性能电解槽堆的设计提供信息。

The active area of PEM electrolyser cells influences current draw, hydrogen production and electrical load capacity. The current largest cell area that can be achieved is solely dictated by the current availability of metal sintered parts. There are significant advantages to be had from utilising larger area electrolyser cells including greater hydrogen generation capacity with reduced integration and control requirements making for a more cost-effective solution and a larger electrical load to be packaged in a smaller system. The project will investigate novel sintered titanium structures for use as large (>1000cm2), electrically conductive liquid diffusion layers for incorporation into rapid response, high-performance polymer electrolyte membrane water electrolysers used for the production of hydrogen for clean fuels and energy storage. Evaluating the performance of large sinters will inform the design of ITM's next generation high performance electrolyser stacks.
