Operation of Direct Methanol Fuel Cells
Electrochemical and Solid-State Letters, 2003A simple and effective procedure is provided to prevent a direct methanol fuel cell from deterioration during overnight idle period. The procedure includes purging cathode and/or anode using a gas before the cell is shut down. The procedure can also be performed before the cell is restarted if purging was not carried out before the cell was shut down ...

Direct methanol fuel cells for transportation
IEE Seminar on Electric, Hybrid and Fuel Cell Vehicles, 2000The author's progress made in the key areas for direct methanol fuel cell (DMFC) development for transport applications is discussed. A large-scale prototype DMFC stack has been built (25 cells of 270 cm/sup 2/ active area per cell, nominal power output 500 W) based on a flow bed design developed by the author with the aid of a flow visualisation study

Catalysts for Direct Methanol Fuel Cells
Fuel Cells, 2002The activity of in house prepared carbon-supported Pt-Ru catalysts for methanol oxidation and carbon-supported RuSe for the oxygen reduction reaction in direct methanol fuel cells (DMFCs) was investigated. The composition of Pt-Ru/C was varied both in terms of weight loading (ratio of total metal content to carbon) as well as the ratio of Pt to Ru. The

Review of Direct Methanol Fuel Cells
2007Direct Methanol Fuel Cells (DMFCs) are galvanic electrochemical flow systems that convert chemical energy from methanol and oxygen directly to electrical energy. This direct conversion avoids the limitations of the Carnot cycle that constrains the performance of engines and gives DMFCs a higher theoretical efficiency.

Catalysis for Direct Methanol Fuel Cells
2012The direct methanol fuel cell (DMFC) is a particular case of a low-temperature proton exchange membrane (PEM) fuel cell (FC). A DMFC utilizes CH3OH as anode fuel and O2 as cathode fuel. Depending on the application, a DMFC is typically operated in the range of 40–80°C.

Direct Use of Methanol in Fuel Cells
Energy Sources, Part A: Recovery, Utilization, and Environmental Effects, 2008Abstract A fuel cell is a device in which the energy of a fuel is converted directly into electricity direct current by an electrochemical reaction without resorting to a burning process, rather than to heat by a combustion reaction. Methanol can be used in blend with conventional fuels without engine modification or pure as a fuel. The direct methanol
