When fuel cells operate for long hours or near salt-laden environments, the coated bipolar plate interface becomes an important part of the durability strategy. SydroSTAR™ is positioned for SUS316L metallic bipolar plates in applications where service intervals, corrosion resilience and the cost of downtime influence component selection.

The FCVA-based carbon coating is designed to retain low interfacial contact resistance while limiting corrosion and metallic-ion release. Within the SydroCOAT™ PEM fuel cell range, SydroSTAR™ focuses on extended duty cycles and greater chloride resilience, making it relevant to heavy-duty trucks and buses, long-running stationary systems, and port or coastal equipment programmes.

Sydrogen works with customers to evaluate the coating against representative plate geometry, exposure conditions and durability objectives. Contact-resistance measurements, electrochemical evaluation, ion-release analysis and coating-integrity checks can be combined into an agreed qualification plan. Share your SUS316L plate design, duty cycle, chloride exposure and service-life objectives to discuss a sample evaluation and the coated-component supply or production route your programme needs.
