  text: “Hydrogen economy” could enable a carbon-neutral sustainable energy chain.
    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.
