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.
