An Alkaline-Acid Glycerol Electrochemical Reformer for Simultaneous Production of Hydrogen and Electricity.

ABSTRACT: This study shows the results, for the first time, of an glycerol alkaline-acid electrolyzer. Such a configuration allows spontaneous operation, producing energy and hydrogen simultaneously as a result of the utilization of the neutralization and fuel chemical energy. The electroreformer-built with a 20 wt% Pd/C anode and cathode, and a Na⁺-pretreated Nafion^® 117-can simultaneously produce hydrogen and electricity in the low current density region, whereas it operates in electrolysis mode at high current densities. In the spontaneous region, the maximum power densities range from 1.23 mW cm^-2 at 30 °C to 11.9 mW cm^-2 at 90 °C, with a concomitant H₂ flux ranging from 0.0545 STP m^-3 m^-2 h^-1 at 30 °C to 0.2
