A two-step consecutive reaction model, an initial dehydrogenation step followed by a CO formation step, is proposed for the dissociation process of the DME molecule. The mechanism of the DME dissociation on the Pt electrode surface is discussed based on the kinetic analysis.Electrochemical SocietyJournal Articleapplication/pdfhttp://hdl.handle.net/2115/42505https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/42505/1/JES000F10.pdf0013-4651AA00697016Journal of The Electrochemical Society1571F10F152010enginfo:doi/10.1149/1.3243847© The Electrochemical Society, Inc. 2010.
