Theoretical analysis of a glycerol reforming and high-temperature PEMFC integrated system: Hydrogen production and system efficiency

► A performance of a glycerol processing and HT-PEMFC integrated system is analyzed. ► Glycerol shows higher hydrogen production and lower carbon formation than methane. ► Increases in the fuel utilization and reformer temperature can improve the HT-PEMFC system efficiency. ► Water obtained from the HT-PEMFC is sufficient to supply to the steam reformer. ► External heat is required to maintain the steam reforming to achieve high system efficiency at high fuel utilization.
