Liam area of research focuses specifically on the bipolar plates present in PEMFCs. A review of current research and materials will be used to direct the vision of new plate coating materials. The plate material will be metallic in nature, current research suggests stainless steel, aluminium and titanium plates are the most viable materials for industry, each with their own merits. A range of coating materials will be investigated, coatings will be assessed by cost, corrosion, contact resistance (at start and end of lifetime tests) and manufacturability. Coatings shall be tested in in-situ and ex-situ experiments. Corrosion will be reviewed using SEM images, the change in contact resistance throughout the lifetime of the cell will also provide insight into the corrosion of the cell. Successful coating materials will look to outperform materials currently in production, it is hoped that a material can be found that will meet or exceed the targets set by the Department of Energy.
