State-of-the-art PEM fuel cells utilise metallic separator plates which require a coating to reduce their contact resistance to acceptable levels. Such coatings are usually applied by PVD which has high capital costs in order to achieve high volume. This feasibility project aims to reduce PEM bipolar plate coating costs by developing high conductivity carbon-based coatings suitable for application by traditional high volume wet coating processes. Methods for depositing thin film coatings onto preformed, roll material for subsequent forming into fuel cell plates will be developed, these will then undergo ex-situ characterisation for adhesion of the coating through the forming operation and contact resistance before in-situ fuel cell testing. In parallel, coating options for formed parts will be devised such that a comparative costing of pre- vs post-forming coating options can be carried out. The project will aim to develop a process which represents a 30% reduction over the volume cost of existing PVD processed materials whilst achieving equivalent to, or better than, incumbent contact resistance, and demonstrating a route to volume realisation.

最先进的PEM燃料电池利用金属隔板，其需要涂层以将其接触电阻降低到可接受的水平。这种涂层通常通过PVD施加，其具有高资本成本以实现高体积。该可行性项目旨在通过开发适用于传统大批量湿涂工艺的高导电性碳基涂层来降低PEM双极板涂层成本。将开发用于将薄膜涂层沉积到预成型的辊材料上以用于随后形成燃料电池板的方法，然后在原位燃料电池测试之前，这些方法将经历通过成形操作的涂层粘附力和接触电阻的非原位表征。与此同时，将设计成型部件的涂层选项，以便对成型前和成型后涂层选项进行比较成本。该项目的目标是开发一种工艺，该工艺比现有PVD加工材料的体积成本降低30%，同时实现相当于或优于现有接触电阻，并展示实现体积的途径。
