Metallic Bipolar Plates are the pathway to mass commercialisation
Bipolar Plates are a critical component of hydrogen fuel cells, representing up to 80% of a fuel cell stack's weight and 50% of cost.
Metallic bipolar plates are the technology of choice for the mass production of fuel cells due to its ability to enable a smaller form factor, weight and scales well with mass-production techniques.
However, metallic bipolar plates easily degrade and passivate in fuel cells, leading to severe reduction performance over its lifespan.
SydroDIAMOND®: Metallic Bipolar Plate Coatings for PEM Fuel Cells
SydroDIAMOND® is a precious metal-free bipolar plate coating that enhances material conductivity and protects substrate materials from passivation.
SydroDIAMOND® is commercialised and in-production for SUS 316L, SUS 304 and Titanium substrates using our unique Filtered Cathodic Vacuum Arc (FCVA) coating technology.
SydroDIAMOND® Coating
Smooth, uniform coatings using FCVA
Alternative Carbon
Coatings
Rougher coatings susceptible to
degradation by conventional PVD
Verified to maintain high Fuel Cell Current Density
SydroDIAMOND® has been demonstrated to maintain a high Fuel Cell current density with lower degradation compared to a reference gold material.
These were tested under cyclical Accelerated Stress Test (AST) conditions.
The AST was conducted by third-party German research institute Zentrum für BrennstoffzellenTechnik GmbH (ZBT), a leading fuel cell research institute in Duisberg, Germany.
