Zero-gap alkaline water electrolyzer (ZGAWE) can produce hydrogen economically and efficiently. Here, we developed a ZGAWE hydrodynamic model and investigated the changes in cell performance according to the input power and different electrode supporter structures, such as wavy mesh, foam, and serpentine, under actual operating conditions. Owing to its high hydrogen conversion rate and low operation costs, the wavy mesh supporter design had the highest efficiency. Additionally, as the system size increased, the operation costs decreased; thus, the wavy mesh supporter design was also applicable for large-scale ZGAWE systems. Foam supporter flow field design shows a very similar trend and can compete with the wavy mesh supporter. Conversely, different hydrodynamic performance and high operation costs of the serpentine flow field design made it unsuitable for the ZGAWE system, but it could be used for the proton/anion exchange membrane water electrolyzer. The results provide significant insights into the hydrodynamic effects to operate ZGAWEs at different cell voltages; additionally, the results can be used to develop high-performance water electrolyzer systems. water electrolyzer zero-gap alkaline water electrolyzer flow field design wavy mesh supporter hydrogen production Full Text Cite Share Download PDF Status: Published Journal Publication published 05 Mar, 2026 Read the published version in Korean Journal of Chemical Engineering → Version 1 posted Reviewers agreed at journal 24 Oct, 2025 Reviewers invited by journal 20 Oct, 2025 Editor assigned by journal 17 Oct, 2025 First submitted to journal 14 Oct, 2025 You are reading this latest preprint version Research Square lets you share your work early, gain feedback from the community, and start making changes to your manuscript prior to peer review in a journal.

emitting carbon-based molecules; thus, it is an environmentally friendly technology. Zero-gap alkaline water electrolyzer (ZGAWE) can produce hydrogen economically and efficiently. Here, we developed a ZGAWE hydrodynamic model and investigated the changes in cell performance according to the input power and different electrode supporter structures, such as wavy mesh, foam, and serpentine, under actual operating conditions. Owing to its high hydrogen conversion rate and low operation costs, the wavy mesh supporter design had the highest efficiency. Additionally, as the system size increased, the operation costs decreased; thus, the wavy mesh supporter design was also applicable for large-scale ZGAWE systems. Foam supporter flow field design shows a very similar trend and can compete with the wavy mesh supporter. Conversely, different hydrodynamic performance and high operation costs of the serpentine flow field design made it unsuitable for the ZGAWE system, but it could be used for the proton/anion exchange membrane water electrolyzer. The results provide significant insights into the hydrodynamic effects to operate ZGAWEs at different cell voltages; additionally, the results can be used to develop high-performance water electrolyzer systems.\u003c/p\u003e","manuscriptTitle":"Effects of the electrode supporter structures for achieving optimum hydrodynamic performance for a zero-gap alkaline water electrolysis cell","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2025-10-30 23:11:00","doi":"10.21203/rs.3.rs-7861804/v1","editorialEvents":[{"type":"communityComments","content":0},{"type":"reviewerAgreed","content":"","date":"2025-10-25T02:54:37+00:00","index":0,"fulltext":""},{"type":"reviewersInvited","content":"","date":"2025-10-21T02:02:43+00:00","index":"","fulltext":""},{"type":"editorAssigned","content":"","date":"2025-10-17T13:38:27+00:00","index":"","fulltext":""},{"type":"submitted","content":"Korean Journal of Chemical Engineering","date":"2025-10-14T16:32:07+00:00","index":"","fulltext":""}],"status":"published","journal":{"display":true,"email":"[email protected]","identity":"korean-journal-of-chemical-engineering","isNatureJournal":false,"hasQc":true,"allowDirectSubmit":false,"externalIdentity":"kjce","sideBox":"Learn more about [Korean Journal of Chemical Engineering](http://link.springer.com/journal/11814)","snPcode":"11814","submissionUrl":"https://www.editorialmanager.com/kjce/default2.aspx","title":"Korean Journal of Chemical Engineering","twitterHandle":"","acdcEnabled":true,"dfaEnabled":true,"editorialSystem":"em","reportingPortfolio":"Springer Subscription","inReviewEnabled":true,"inReviewRevisionsEnabled":false}}],"origin":"","ownerIdentity":"212220b3-beda-4c77-9a1f-3690ae391c09","owner":[],"postedDate":"October 30th, 2025","published":true,"recentEditorialEvents":[],"rejectedJournal":[],"revision":"","amendment":"","status":"published-in-journal","subjectAreas":[],"tags":[],"updatedAt":"2026-03-09T16:14:05+00:00","versionOfRecord":{"articleIdentity":"rs-7861804","link":"https://doi.org/10.1007/s11814-026-00664-9","journal":{"identity":"korean-journal-of-chemical-engineering","isVorOnly":false,"title":"Korean Journal of Chemical Engineering"},"publishedOn":"2026-03-05 15:58:20","publishedOnDateReadable":"March 5th, 2026"},"versionCreatedAt":"2025-10-30 23:11:00","video":"","vorDoi":"10.1007/s11814-026-00664-9","vorDoiUrl":"https://doi.org/10.1007/s11814-026-00664-9","workflowStages":[]},"version":"v1","identity":"rs-7861804","journalConfig":"researchsquare"},"__N_SSP":true},"page":"/article/[identity]/[[...version]]","query":{"redirect":"/article/rs-7861804","identity":"rs-7861804","version":["v1"]},"buildId":"8U1c8b4HqxoKbykW_rLl7","isFallback":false,"isExperimentalCompile":false,"dynamicIds":[84888],"gssp":true,"scriptLoader":[]}
