# Smoltek Hydrogen Partners with Heraeus to Boost Iridium Efficiency in PEM Electrolyzers

Smoltek Hydro­gen, spe­cial­iz­ing in inno­v­a­tive solu­tions based on car­bon nan­otech­nol­o­gy, and Her­aeus Pre­cious Met­als, a glob­al leader in pre­cious met­al solu­tions, have signed a term sheet on a strate­gic col­lab­o­ra­tion on advanced irid­i­um-based cat­a­lyst solu­tions for pro­ton exchange mem­brane (PEM) elec­trolyz­ers.  
   
This col­lab­o­ra­tion marks a sig­nif­i­cant step toward devel­op­ing the next gen­er­a­tion of PEM elec­trolyz­er tech­nol­o­gy, sup­port­ing the glob­al ener­gy tran­si­tion with scal­able and sus­tain­able solutions.

**Boost­ing the func­tion­al effi­cien­cy of PTEs for next-gen PEMWEs**

> By com­bin­ing our nanos­truc­ture tech­nol­o­gy with Her­aeus’ exper­tise in advanced cat­a­lyst for­mu­la­tions, we aim to fur­ther push the lim­its of irid­i­um effi­cien­cy in PEM elec­trolyz­ers, paving the way for cost-effec­tive green hydro­gen production.

> *Elli­nor Ehrn­berg, Pres­i­dent of Smoltek Hydrogen*

The coop­er­a­tion part­ners will com­bine their knowl­edge to advance the func­tion­al of porous trans­port elec­trodes (PTEs), rep­re­sent­ing the next gen­er­a­tion elec­trodes for PEM electrolyzers.

> Col­lab­o­rat­ing with Smoltek Hydro­gen allows us to com­bine their inno­va­tion speed with our indus­tri­al expe­ri­ence and scale. Togeth­er, we aim to achieve a sig­nif­i­cant leap in cat­a­lyst effi­cien­cy and pro­vide solu­tions that meet the needs of a grow­ing hydro­gen market.

Smoltek’s Nanos­truc­tured Low Irid­i­um-Load PTE

**Strong syn­er­gies**  
The part­ner­ship reflects the strong syn­er­gies between Her­aeus’ glob­al indus­tri­al exper­tise and Smoltek’s inno­v­a­tive solu­tions based on car­bon nan­otech­nol­o­gy. It also high­lights the increas­ing impor­tance of reduc­ing irid­i­um depen­den­cy in the hydro­gen indus­try, as glob­al demand for PEM elec­trolyz­ers con­tin­ues to rise..

> Her­aeus’ unique low-irid­i­um cat­a­lyst solu­tions have made them known as the tech­nol­o­gy leader by every­one in the PEM elec­trol­y­sis busi­ness. Plac­ing this on our nanofibers, which also are designed for ultra-low irid­i­um con­tent, should be a break­through cre­at­ing echoes in the whole industry.
