Add to compare

Fuel Cell - Carbon is a low-cost coating for metallic bipolar plates in fuel cells, designed to enable electrical conductivity and protect stainless steel plates from metal leaching, which can poison the membrane and reduce stack performance over time. The coating is deposited using sputter PVD technology, with plasma surface cleaning and a special metal-based adhesion layer for optimal durability and performance under various conditions, including cold starts and extreme conditions. It meets the requirements for stable, reliable performance and acceptable price performance in automotive fuel cell applications.
