摘要：
Hydrogen production via coal electrolysis was evaluated at intermediate temperatures (40-108 degrees C). A coal electrolytic cell (CEC) was designed and constructed to carry out galvanostatic experiments with concentrated electrolyte (4M H2SO4)- Operating temperatures above 100 degrees C were found to significantly improve the kinetics of electro-oxidation of coal, coal conversion, and CO2/coal Faradaic efficiency. CO2/coal Faradaic efficiencies and coal conversions of up to 57.29 and 3.21%, respectively, were observed at 108 degrees C. (C) 2007 Elsevier B.V. All rights reserved.
