However, issues with safety, storage, and transport of molecular hydrogen impede its realization. Alcohols as liquid H2 carriers could be enablers, but state-of-the-art reforming is difficult, requiring high temperatures >200 °C and pressures >25 bar, and the resulting H2 is carbonized beyond tolerance levels for direct use in fuel cells. Here, we demonstrate ambient temperature and pressure alcohol reforming in a fuel cell (ARFC) with a simultaneous electrical power output. The alcohol is oxidized at the alkaline anode, where the resulting CO2 is sequestrated as carbonate. Carbon-free H2 is liberated at the acidic cathode. The neutralization energy between the alkaline anode and the acidic cathode drives the process, particularly the unusually high entropy gain (1.27-fold ΔH). The significantly positive temperature coefficient of the resulting electromotive force allows us to harvest a large fraction of the output energy from the surrounding, achieving a thermodynamic efficiency as high as 2.27. MoS2 as the cathode catalyst allows alcohol reforming even under open-air conditions, a challenge that state-of-the-art alcohol reforming failed to overcome. We further show reforming of a wide range of alcohols. The ARFC offers an unprecedented route toward hydrogen economy as CO2 is simultaneously captured and pure H2 produced at mild conditions.","lang":"eng"}],"department":[{"_id":"StFr"}],"day":"11","type":"journal_article","date_updated":"2023-08-07T13:43:19Z","article_processing_charge":"No","month":"02","status":"public","quality_controlled":"1","title":"Ambient condition alcohol reforming to hydrogen with electricity output","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","date_created":"2021-02-12T09:20:18Z","oa_version":"None","scopus_import":"1","publisher":"American Chemical Society","citation":{"ieee":"Z.
