Performance Modeling of a Direct Methanol Fuel Cell Fueled With Methanol and Ethanol
Journal of Fuel Cell Science and Technology, 2014Direct methanol fuel cells (DMFCs) are becoming a choice of a power source in the field of power electronics, and portable devices because of their high energy density. The benefits of using a fuel cell toward the environment will be enhanced if the fuel used for its application comes from renewable sources such as ethanol.

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

Pyramidal direct methanol fuel cells
International Journal of Heat and Mass Transfer, 2006Abstract The main concept of this article is to allow for the optimized tree-like design of the flow distributors to actually define the shape of the fuel cell, thereby eliminating problems associated with the mismatch between a predecided rectangular shape and a functionally preferred channel distribution system.

Performance of a Direct Methanol Fuel Cell
Journal of Electrochemistry, 2001A direct methanol fuel cell with 9cm2 active area consists of Pt-Ru/C anode ,Pt/Ccathode and Nafion 115 membrane. The effect of operating conditions: methanol solution concentration, oxygen pressure and cell temperature on the cell performances was investigated. The results show that performance of single cell was enhanced by increasing oxygen pressure

Performance of a direct methanol fuel cell
Journal of Applied Electrochemistry, 1998The performance of a direct methanol fuel cell based on a Nafion® solid polymer electrolyte membrane (SPE) is reported. The fuel cell utilizes a vaporized aqueous methanol fuel at a porous Pt–Ru–carbon catalyst anode. The effect of oxygen pressure, methanol/water vapour temperature and methanol concentration on the cell voltage and power output is ...

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.

Sensors for direct methanol fuel cells
Renewable and Sustainable Energy Reviews, 2014Abstract A sensor can be used to enhance the performance of a direct methanol fuel cell (DMFC). Sensors function as alarms for various problems encountered with DMFCs, of which methanol crossover is the primary problem. These sensors can significantly improve DMFC operation, thereby promoting the commercialisation of this product.

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 ...
