Smoltek Hydro­gen is attend­ing the 247th ECS Meet­ing in Mon­tréal, Cana­da. The event brings togeth­er the most active researchers in acad­e­mia, gov­ern­ment, and indus­try to engage, dis­cuss, and inno­vate in the areas of elec­tro­chem­istry and sol­id state sci­ence and relat­ed technologies.

By show­ing that we can run a PEMWE with only 0.1 mg/​cm2 of irid­i­um, 2 A/​cm2 pro­ton cur­rent den­si­ty for 250 hours of con­tin­u­ous oper­a­tion – we are unlock­ing green hydro­gen at the man­u­fac­tur­ing scale of tens of gigawatts each year! This is the key to decar­bonize steel and base chem­i­cals for a pros­per­ing planet.

Fabi­an Wenger, Head of R&D

Smoltek Hydro­gen has suc­cess­ful­ly reduced the load­ing of Ir-based cat­a­lyst to 0.1 mg iridium/​cm2, with­out com­pro­mis­ing the over­all per­for­mance of the PEM elec­tolyz­er. The reduc­tion of irid­i­um is crit­i­cal in order to enable glob­al mass man­u­fac­tur­ing tar­gets for green hydro­gen pro­duc­tion using PEM electrolysis.

Smoltek Hydro­gen’s unique Porous Trans­port Elec­trode (PTE):

• Max­i­miz­ing the avail­able sur­face area
• Max­i­miz­ing Ir cat­a­lyst uti­liza­tion, achiev­ing load­ing lev­els as low as 0.1 mg/​cm2
• Reduc­ing con­tact resis­tance between the cat­a­lyst lay­er and the PTL substrate

Results and roadmap ahead will be presented:

• Palais des Con­grès de Mon­tréal, Room 516D (5th Floor)
• May 20, 2025 at 15:10

Smoltek Hydro­gen PTE tech­ni­cal scope: The low elec­tri­cal resis­tiv­i­ty and high mechan­i­cal strength indi­cate why cor­ro­sion coat­ed nanofibers are an attrac­tive cat­a­lyst sup­port mate­r­i­al. The solu­tion offered by Smoltek Hydro­gen takes full advan­tage of the excep­tion­al nanofiber prop­er­ties on a PTL. This method 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.
