Sheet compression moulding

The manufacturing of graphite bipolar plates for fuel cells via sheet compression moulding involves a process where a graphite sheet is first cut into a specific shape and size. The sheet is then coated with a binder material, typically a resin or polymer, which acts as an adhesive for the graphite particles.

Next, the coated graphite sheet is layered into a mold and subjected to high temperature and pressure. This process causes the binder material to melt and fuse the graphite particles together into a solid structure, creating a graphite bipolar plate.

After the compression moulding process, the plate is further machined and processed to achieve the final desired shape and dimensions. This can include steps such as trimming, drilling, and coating the plate with a protective layer.

The use of sheet compression moulding in the manufacturing process of graphite bipolar plates offers several benefits. It allows for greater flexibility in the design and production of the plates, as well as the ability to create plates in large quantities with high precision and consistency. Additionally, this method is cost-effective and efficient, as it minimizes waste material and reduces production time.

Overall, the use of sheet compression moulding in the manufacturing of graphite bipolar plates for fuel cells is a reliable and efficient method that ensures high-quality and consistent production.

IAG is creating solutions with other partners to allow for the upcoming mass production of million units. Using development tools and many material options, customers are involved in the ultimate solution's development. This strategy will eventually result in the introduction of a machine that can produce in large quantities.
