Proton exchange membrane (PEM) water electrolyser is considered as the most promising technique to produce highly pure hydrogen from renewable energy sources and has reached the early stages of commercial deployment, the remaining challenges include the need to lower the production cost and to increase the cell durability. Porous transport layer (PTL) plays an important role in cell performance and durability. In general, Titanium based material is applied as PTL in the anode side of PEM water electrolyser. However, titanium easily forms a thin layer of oxide on the surface and it will reduce the electrical conductivity. Therefore, PTLs are coated with high amounts of precious metals to ensure proper performance for long-term operation which is the high capital expense of PEM water electrolyser. To overcome this challenge, low-cost coating with high durability should be developed to accelerate the mass production of this technology. In this project, precious metals will be replaced with niobium-based materials and different treatment and doping will be investigated to select the best coating with superior properties. This project is well aligned with Quebec and Canada hydrogen strategy and will create jobs and new knowledge in hydrogen field. It is expected upon the successful completion of the proposed research project, further scale up of the down-selected research results will be carried out for scaled up samples.

质子交换膜（PEM）水电子被认为是从可再生能源产生高度纯净氢的最有希望的技术，并且已经达到了商业部署的早期阶段，其余的挑战包括降低生产成本并提高细胞耐用性。多孔运输层（PTL）在细胞性能和耐用性中起重要作用。通常，将基于钛的材料作为PTL应用于PEM水电解剂的阳极侧。 但是，钛很容易在表面形成薄薄的氧化层，它将降低电导率。因此，PTL涂有大量的贵金属，以确保长期运行的适当性能，这是PEM水电机的高资本费用。为了克服这一挑战，应开发具有高耐用性的低成本涂层，以加速该技术的大规模生产。在这个项目中，贵金属将被基于尼伯的材料代替，并且将研究不同的处理和掺杂，以选择具有出色特性的最佳涂层。该项目与魁北克和加拿大氢策略非常一致，将在氢场创造就业机会和新知识。预计在拟议的研究项目成功完成后，将进一步扩大缩小的研究结果，以缩放样本。
