The eHy-1002 is a porous IrO₂ anode catalyst for PEM water electrolysis. It targets the limitations of conventional rutile IrO₂ by combining a highly regular, layered porous morphology with about 74% porosity, which increases exposure of active iridium edge sites and improves mass transfer, charge transfer, and intrinsic OER activity. The bulk iridium content is reduced to approximately 70 wt%, lowering dependence on this precious metal.
At an MEA iridium loading of 0.75 mg/cm², the catalyst delivers 1.96 V at 4 A/cm² using Nafion N115 at 80°C, and shows long-term stability with more than 15,000 hours of operation and a voltage rise below 3 μV per hour. Additional durability data include single-cell stability beyond 10,000 hours at 1–2 A/cm² and stack stability beyond 1,500 hours at 1.5 A/cm². The product has undergone multiple customer validations, with current production capacity around 600 g per day. For key accounts, the company provides catalyst slurry formulation and coating process guidance.
