The inkjet deposition approach enabled deposition of ultra-low Pt loadings (range of 0.00036–0.0096 mg Pt cm<sup>−2</sup>), representing high Pt utilisation.

Additionally, a positive onset potential under illumination for the HER was observed for the CuS-Pt/C films (up to approximately 0.025 V vs. RHE) compared to that of the bare CuS film (ca. −0.013 V vs. RHE), indicating co-catalytic contribution of the Pt in the Pt/C materials for the improvement of the HER.

The current study offers a thorough evaluation of additive manufacturing’s (AM) ability to produce PEM fuel cell components, providing important information to direct the development of clean energy technologies in the future.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":665,"journal":{"name":"Journal of Solid State Electrochemistry","volume":"30 7","pages":"2381 - 2403"},"PeriodicalIF":3.1,"publicationDate":"2026-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148357843","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
