According to foreign media reports, Intelligent Energy and the Center for Process Innovation (CPI) and coating supplier Haydale have partnered to develop a proton exchange membrane (PEM) fuel cell bipolar plate Developed a new conductive coating designed to further reduce costs.
The smart energy company is leading the research project to jointly develop new conductive coatings using nanocarbon materials instead of the traditional physical vapor deposition (PVD).
Traditional PEM fuel cell metal bipolar plates usually require a conductive coating to minimize resistive losses. These coatings are either batch-coated or are manufactured using high-tech processes such as thermal spraying, chemical vapor deposition (CVD) and the most commonly used physical vapor deposition process.
However, the above method is costly, requires a large number of personnel to be involved in loading and unloading work, has a long processing time to realize a high vacuum, and requires a large amount of capital investment for continuous vacuum processing.
The one-year NovCoat project is responsible for assessing the technical feasibility and cost savings of using low-cost, wet-coating technology.
The project develops advanced coatings using functionalized nanocarbons (graphite and / or carbon nanotubes) as primary conductive components that enhance the Z-plane conductivity to meet US Department of Energy standards for vehicle-grade materials .
The NovCoat project successfully achieved nano-carbon coating on stainless steel to make it behave like a PVD coating and achieve roll-to-roll processes based on environmental conditions and protocols that will help drive output levels , And significantly reduce costs.
