“…Therefore, proposing an effective approach to address it is reasonable for validating the above conclusions and achieving the purpose of performance improvement. Pt nanoparticles, a commonly used material in the hydrogen energy field with good compatibility in the catalytic slurry system of PEMWE as well as excellent electrical conductivity, were used here to regulate the homogeneity and also conductivity in the catalyst layer [ 58 ]. The newly constructed catalyst layer was assembled to MEA, and the corresponding PEMWE performance is shown in Figure 4 a.…”

PEMWE is becoming one of the most promising technologies for efficient and green hydrogen production, while the anode OER process is deeply restricted by the now commercially used iridium oxide with sluggish reaction kinetics and super high cost. Deeply exploring the essential relationship between the underlying substrate materials and the performance of PEMWE cells while simultaneously excavating new practical and convenient methods to reduce costs and increase efficiency is full of challenges. Herein, two representative kinds of iridium oxide were studied, and their performance difference in PEMWE was precisely analyzed with electrochemical techniques and physical characterization and further linked to the ionomer/catalyst compound features. A novel anode with a uniform thin ionomer coating was successfully constructed, which simultaneously optimized the ionomer/catalyst aggregates as well as electrical conductivity, resulting in significantly enhanced PEMWE performance. This rigorous qualitative analysis of the structure–performance relationship as well as effective ionomer-affinitive optimization strategies are of great significance to the development of next-generation high-performance PEM water electrolyzers.

“…To address this challenge, considerable efforts have been directed toward reducing Pt loading or finding substitutes utilizing earth-abundant materials. Currently, 40 wt % Pt/C stands as the prevalent commercial HER catalyst for PEMWEs, with Pt loading lowered to 0.4–0.6 mg cm –2 . , While Pt/C has succeeded in reducing Pt content, its utilization in MEA for large-scale applications remains financially prohibitive.…”
