Smoltek Hydro­gen is attend­ing the joint inter­na­tion­al meet­ing of Elec­tro­chem­i­cal and Sol­id-State Sci­ence. The meet­ing is arranged by Elec­tro­chem­i­cal Soci­ety Japan, Elec­tro­chem­i­cal Soci­ety Korea and the PRiME 2024/​246th ECS Meet­ing and will be held in Hon­olu­lu, HI.

Smoltek Hydro­gen is pro­gress­ing towards enhanc­ing water elec­trolyz­er (PEMWE) per­for­mance with 0.1 mg/​cm² irid­i­um load­ing using our inno­v­a­tive porous trans­port elec­trodes (PTEs). By opti­miz­ing PEMWE assem­bly and refin­ing the oper­at­ing con­di­tions for PTEs, we are rapid­ly approach­ing the US Depart­ment of Ener­gy (DOE) targets.

Enabling green hydro­gen pro­duc­tion on GW scale

Cur­rent­ly, we have achieved per­for­mance of 2.5 A/​cm² at less than 2V (~80% cell effi­cien­cy), with an irid­i­um load­ing of 0.2 mg/​cm². Our cur­rent focus is on address­ing the knowl­edge gap in low-irid­i­um load­ing for the anode cat­a­lyst lay­er (ACL) with our PTEs, par­tic­u­lar­ly regard­ing proton/​electron and water/​gas trans­port and ensure sta­ble oper­a­tion for more than 1,000 hours under indus­tri­al con­di­tions. The results will help us to run dura­bil­i­ty tests at an irid­i­um load­ing of 0.1 mg/​cm² and sur­pass the pre­vi­ous record.

Smoltek Hydro­gen presents: Improv­ing Per­for­mance of PEM Water Elec­trol­y­sis Uti­liz­ing Nanofiber-Enhanced Porous Trans­port Elec­trodes with Low Irid­i­um Con­tent
When: Wednes­day, 9 Octo­ber 2024, 14:40–15:00 Hawaii Stan­dard Time (HST)
Where: Room 312 (lev­el 3, Hawaii Con­ven­tion Cen­ter)
Con­fer­ence code: I01-B2828

More­over, the recent break­through with A4-sized sub­strates has fur­ther accel­er­at­ed Smoltek Hydro­gen’s vision of enabling green hydro­gen pro­duc­tion on a GW scale with low­er pre­cious met­al loadings.

The Prime 2024 (246th ECS) 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.

- See you in Hon­olu­lu, Octo­ber 6–11! 

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 (above illus­tra­tion). 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.
