| Abstract
| - The process and reaction mechanism of propane dehydrogenation in a proton-conducting fuel cell were studied at 600−700 °C using Y-doped BeCeO3 as protonic electrolyte and Pt as electrode catalysts. The electrochemical dehydrogenation of propane was in competition with side reactions caused by the gas species (H2, C2H6, C2H4 etc.), which were the products of nonelectrochemical reactions (e.g., thermal cracking) in the anode chamber. Among those side electrochemical reactions, hydrogen disassociation into hydrogen ions was predominant. At 650 °C electrochemical dehydrogenation of propane has a higher activation energy than hydrogen disassociation over the anode platinum catalyst; however, the former reaction was more readily achieved at 700 °C.
