Production of hydrogen from ethanol with high hydrogen yield and high energy efficiency was per-formed by using an electrochemical catalytic reforming (ECR) approach over the Ni-based catalyst. ECR was carried out in the fixed-bed continuous flow reactor, where an ac electronic current passed through the catalyst. It was found that the performance of the ethanol reforming not only depended on the reforming temperature, but also was remarkably enhanced by the current through the catalyst. In particular, the hydrogen yield and its selectivity significantly increased with an increase in the current in ECR. The promoting effects of the current on the decomposition of ethanol were also studied via the homogeneous experiments and low-pressure time-of-flight measurements. The alteration of the catalyst after the ECR processes was investigated via X-ray diffraction, transmission electron microscopy, and Brunauer-Emmett-Teller measurements. The mechanism of the electrochemical catalytic reforming of ethanol was discussed on the basis of the above investigation.
