  2. 1. The Anode in the Direct Methanol Fuel Cell

    Author : Joakim Nordlund; KTH; []
    Keywords : direct methanol fuel cell; fuel cell; DMFC; anode; model;

    Abstract : The direct methanol fuel cell (DMFC) is a very promisingpower source for low power applications. High power and energydensity, low emissions, operation at or near ambientconditions, fast and convenient refuelling and a potentiallyrenewable fuel source are some of the features that makes thefuel cell very promising.

  4. 2. Mathematical Modeling of Transport Phenomena in Polymer Electrolyte and Direct Methanol Fuel Cells

    Author : Erik Birgersson; KTH; []
    Keywords : Fuel Cell; DMFC; PEFC; model; visual cell; scale analysis; one-phase; two-phase;

    Abstract : This thesis deals with modeling of two types of fuel cells:the polymer electrolyte fuel cell (PEFC) and the directmethanol fuel cell (DMFC), for which we address four majorissues: a) mass transport limitations; b) water management(PEFC); c) gas management (DMFC); d) thermal management. Four models have been derived and studied for the PEFC,focusing on the cathode. READ MORE

  6. 4. Electrooxidation of glycerol and methanol on gold

    Author : Mikael Valter; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; van der Waals; electrochemistry; methanol; gold; glycerol; DFT;

    Abstract : Burning of fossil fuels leads to excess CO2 in the atmosphere, causing global warming, threatening civilisation and ecosystems worldwide. As a step in making the society fossil-independent, we need to replace oil, coal, and gas in the transportation sector with fuels originating from sustainable energy. READ MORE

  7. 5. Development of Methanol-Reforming Catalysts for Fuel Cell Vehicles

    Author : Johan Agrell; KTH; []
    Keywords : PEM fuel cells; hydrogen; methanol; reforming; oxidation; reaction pathways; carbon monoxide;

    Abstract : Vehicles powered by proton exchange membrane (PEM) fuelcells are approaching commercialisation. Being inherently cleanand efficient sources of power, fuel cells constitute asustainable alternative to internal combustion engines to meetfuture low-emission legislation. READ MORE
