Catalyst-Coated Porous Transport Electrode (PTE)

Building on our advanced SP-PTL platform, Verdeon Energy offers a cutting-edge Porous Transport Electrode (PTE) for PEM water electrolysis, developed in collaboration with Momenta Energy.
This innovative anode PTE is created by applying a uniform layer of iridium-based catalyst onto our highly ordered titanium-based SP-PTL using a proprietary coating process. The result is a structure with optimized pore geometry that accelerates reactant transport at the triple-phase boundary, enhancing performance in hydrogen production.
