Iris: The World’s Most Powerful Iridium Catalyst
Reduced Iridium loadings no longer come with reduced performance. Iris’ unique structure enables exccelent CCM durability and electrical contact to the PTL. The result is unparalleled performance and durability
Carefully optimized over a hundred iterations
Calicat’s Iris is a groundbreaking new OER catalyst that offers unprecedented performance at low-Iridium loadings. This catalyst has been rigorously tested under elevated temperature and current density and demonstrates exceptional performance at Iridium loadings below 0.2mg/cm2.
Calicat’s Iris maintains cell voltages below 1.7V at 3A/cm2.
This catalyst greatly exceeds the US DOE benchmark of 1.8V at 3A/cm2 under these MEA conditions and catalyst loadings.
Voltage degradation rate is below 1 uV/hr. DOE 2026 target is 2.3 uV/hr.
Battle Tested Under Harsh Conditions
Iris has been rigourously tested under high pressure, high current density, and low temperature; all at once.
Stress Testing at 25 Bar Differential Pressure
Developed with scalability in mind, Iris is available in small quantities now and in commercial volume by 2027.
