Efficient use of iridium can boost green hydrogen production in this decade and Smoltek Hydrogen wants to seize the opportunity by offering a nanostructured porous transport electrode that reduces cost and optimizes use of the critical anode catalyst in PEM electrolysis cells.
In OctoÂber 8–12 you can take the opporÂtuÂniÂty to meet the Smoltek HydroÂgen team of experts at the 244th ElecÂtroÂchemÂiÂcal SociÂety MeetÂing in GothenÂburg, SweÂden to learn more about our techÂnolÂoÂgy, our H2LAB and the road to volÂume processÂes for green hydroÂgen at scale.
We welÂcome you at the techÂniÂcal exhibÂit (booth #108) or meet with one of our sciÂenÂtists at the conÂferÂence: Xin Wen, Bastien PenÂninckx, Jaime Sanchez, Sankar Sasidharan.
See you in GothenÂburg, 8–12 October!

TechÂnoÂlogÂiÂcal scope: The low elecÂtriÂcal resisÂtivÂiÂty and mechanÂiÂcal strength indiÂcate why CNF are an attracÂtive catÂaÂlyst supÂport mateÂrÂiÂal. The soluÂtion offered by Smoltek HydroÂgen takes full advanÂtage of the propÂerÂties of CNF and the opporÂtuÂniÂties affordÂed by PECVD growth by growÂing verÂtiÂcal CNF on a PTL (above image). This method ensures conÂtact between the CNF and the PTL while proÂvidÂing a high surÂface area subÂstrate. CatÂaÂlyst can then be depositÂed on top of this subÂstrate. The verÂtiÂcal oriÂenÂtaÂtion of the CNF facilÂiÂtates coatÂing of the surÂface with addiÂtionÂal layÂers of mateÂrÂiÂal, such as corÂroÂsion proÂtecÂtion layÂers or catÂaÂlyst particles.
