Abstract：

Formaldehyde　(HCHO),　a　promising　yet　challenging　hydrogen　carrier,　offers　a　unique　opportunity　for　efficient　hydrogen　generation　through　electro-oxidation,　simultaneously　eliminating　harmful　HCHO　and　contributing　to　environmental　sustainability.　This　study　rises　to　the　challenge　by　pioneering　a　hybrid　acid/alkali　formaldehyde　hydrogen　production　fuel　cell　(h-AAFHFC),　an　integrated　system　that　integrates　anodic　partial　electro-reforming　of　aldehydes　at　low　potential　with　the　cathodic　hydrogen　evolution　reaction　(HER).　The　device　introduces　a　new　self-powered　paradigm　for　hydrogen　generation,　driven　by　electrochemical　neutralization　energy　(ENE),　featuring　high　Faradaic　efficiency　for　hydrogen　production,　co-generation　of　electricity,　and　HCOOH.　The　h-AAFHFC　attains　an　open-circuit　voltage　(OCV)　of　1.11 V　and　a　peak　power　density　of　94 mW　cm−2,　enabling　simultaneous　hydrogen　production　at　both　electrodes　with　an　extraordinary　Faradaic　efficiency　of　approximately　200%.　This　breakthrough　marks　a　transformative　shift,　moving　from　traditional　electricity-driven　systems　to　self-sustaining　H2　generation.　Our　work　demonstrates　a　promising　pathway　for　sustainable　hydrogen　production,　advancing　the　potential　of　clean　hydrogen　energy　technologies.　©　2025　Wiley-VCH　GmbH.
