Here, we report a connected-crack MPL architecture that forms continuous liquid water highways, extending from the catalyst layer (CL) to the GDL backing layer, effectively separating the liquid/gas transport. Three-dimensional reconstruction using X-ray computed tomography reveals that the microengineered cracks significantly reduce flooding at the CL-MPL interface by providing efficient drainage. Compared to the noncrack GDL, the connected-crack GDL (C-GDL) exhibits 20% higher peak power density of 1.23 W cm<sup>–2</sup>. Pore-scale simulations further validate the antiflooding capabilities of C-GDL, showing a 25-fold enhancement in water removal. This crack-engineered GDL thus offers an efficient and scalable route to water management challenges, enabling robust and high-performance PEFCs suitable for heavy-duty vehicle electrification.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"12 1","pages":""},"PeriodicalIF":22.0,"publicationDate":"2025-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144278768","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the utilization of these two energy sources is challenged by their conflicting spectral requirements, making it difficult to capture both in a single device or material. Here, an adaptive energy harvester coupling photothermal conversion and radiative cooling utilizing photonic metastructure electrodes in conjunction with reversible metal electrodeposition technology for all-day continuous energy harnessing is reported. The harvester demonstrates sustained bistability for over 30 days with large emissivity contrast (0.82 at 3–5 μm, 0.66 at 7.5–13 μm), robust environmental durability, and scalability (100 cm<sup>2</sup>) for switching between heating and cooling states. World-wide energy simulations show that it can significantly reduce energy consumption in buildings by up to 21.4%, amounting to a savings of 95.8 GJ year-round. This harvester offers a promising method to utilize heat source and heat sink, sun and outer space, to improve sustainability and reduce carbon foot print of the Earth.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"7 1","pages":""},"PeriodicalIF":22.0,"publicationDate":"2025-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144278767","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
