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 October 8–12 you can take the opportunity to meet the Smoltek Hydrogen team of experts at the 244th Electrochemical Society Meeting in Gothenburg, Sweden to learn more about our technology, our H2LAB and the road to volume processes for green hydrogen at scale.
We welcome you at the technical exhibit (booth #108) or meet with one of our scientists at the conference: Xin Wen, Bastien Penninckx, Jaime Sanchez, Sankar Sasidharan.
See you in Gothenburg, 8–12 October!

Technological scope: The low electrical resistivity and mechanical strength indicate why CNF are an attractive catalyst support material. The solution offered by Smoltek Hydrogen takes full advantage of the properties of CNF and the opportunities afforded by PECVD growth by growing vertical CNF on a PTL (above image). This method ensures contact between the CNF and the PTL while providing a high surface area substrate. Catalyst can then be deposited on top of this substrate. The vertical orientation of the CNF facilitates coating of the surface with additional layers of material, such as corrosion protection layers or catalyst particles.
