Smoltek Hydrogen is attending WISE Dialogue meeting 2025, in Münchenbryggeriet, Stockholm, and we are participating in the poster session, to showcase our progress towards minimizing the iridium load in electrodes (PTEs) for PEMWE – to just 0.1 mg/cm2.
Enabling green hydrogen production on GW scale
Exciting progress in PEM electrolyzer performance! Advancing green hydrogen one step closer to scalability.
We’ve recently achieved 2.5 A/cm² at <2V (~80% cell efficiency) with an ultra-low iridium loading of just 0.1 mg/cm². Our focus now is on bridging the knowledge gap in low-iridium anode catalyst layers (ACL) within our PTEs—optimizing proton/electron transport, water/gas management, and ensuring stability under industrial conditions.

Smoltek Hydrogen Porous Transport Electrode technical scope:
The low electrical resistivity and high mechanical strength indicates why corrosion protected nanofibers are an attractive catalyst support material for Iridium deposition. The solution offered by Smoltek Hydrogen takes full advantage of the exceptional nanofiber properties on a PTL,while maintaining the porosity. The current method of PTE fabrication ensures full contact between the nanofibers and the PTL while providing a high surface area substrate and catalysts can then be deposited on top of this substrate. The vertical orientation of the nanofibers facilitates coating of the surface with additional layers of material, such as corrosion protection layers or catalyst particles.
