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.
