Direct Dimethyl Ether Fuel Cell with Much Improved Performance
Due to several apparent advantages over methanol, dimethyl ether (DME) has been viewed as a promising alternative fuel for direct fuel cell technology. Similar to methanol, DME oxidation requires a surface oxidant, such as OH, for the removal of adsorbed CO. Consequently, the reaction occurs at much faster rates on binary PtRu catalysts than Pt alone. In this work, PtRu catalysts with a wide va...
متن کاملAnode Catalysts for the Direct Dimethyl Ether Fuel Cell
For the last decade, dimethyl ether (DME) has been considered a promising alternative fuel for direct fuel cells because of several advantages over methanol. In this work, PtRu catalysts with a wide range of Pt-to-Ru ratios were screened for the direct DME fuel cell (DDMEFC) performance for the first time. Overall, Pt50Ru50 performs best in the high and middle voltage ranges, whereas Pt80Ru20 p...
متن کاملHigh-activity PtRuPd/C catalyst for direct dimethyl ether fuel cells.
Dimethyl ether (DME) has been considered as a promising alternative fuel for direct-feed fuel cells but lack of an efficient DME oxidation electrocatalyst has remained the challenge for the commercialization of the direct DME fuel cell. The commonly studied binary PtRu catalyst shows much lower activity in DME than methanol oxidation. In this work, guided by density functional theory (DFT) calc...
متن کاملEmission Characteristics of Jatropha - Dimethyl Ether Fuel Blends on A DI Diesel Engine
In this study, Biodiesel -Dimethyl Ether (BDE ) was tested in a 4-cylinder direct-injection diesel engine to investigate the performance and emission characteristics of the engine under five engine loads at the maximum torque .The engine speed was maintained at 1500 rpm. Here the jatropha oil is used as a non edible oil to produce the biodiesel. The dimethyl ether is used as an additive to enha...
متن کاملElectrochemical and flow characterization of a direct methanol fuel cell
Two-phase phenomena, i.e. bubble flow in the anode and water flooding in the cathode, are critical to design of high-performance direct methanol fuel cells (DMFC). A 5 cm2 transparent DMFC has been developed to visualize these phenomena in situ. Two types of membrane-electrode assembly (MEA) based on Nafion® 112 were used to investigate effects of backing pore structure and wettability on cell ...
