IV.J.4 Advanced Catalysts for Direct Methanol Fuel Cells
Approach • Develop a methodology that provides high-throughput fabrication and analyses of novel alloy materials of arbitrary composition. • Evaluate multi-component alloys consisting of platinum, ruthenium, nickel and zirconium that are corrosion-resistant in acid for catalytic activity. • Analyze results of polarization studies to develop a rationale for catalyst performance. • Evaluate promi...
متن کاملBifunctional anode catalysts for direct methanol fuel cells
Using the binding energy of OH* and CO* on close-packed surfaces as reactivity descriptors, we screen bulk and surface alloy catalysts for methanol electro-oxidation activity. Using these two descriptors, we illustrate that a good methanol electro-oxidation catalyst must have three key properties: (1) the ability to activate methanol, (2) the ability to activate water, and (3) the ability to re...
متن کاملPalladium-Based Catalysts as Electrodes for Direct Methanol Fuel Cells: A Last Ten Years Review
Platinum-based materials are accepted as the suitable electrocatalysts for anodes and cathodes in direct methanol fuel cells (DMFCs). Nonetheless, the increased demand and scarce world reserves of Pt, as well as some technical problems associated with its use, have motivated a wide research focused to design Pd-based catalysts, considering the similar properties between this metal and Pt. In th...

متن کاملLiquid methanol concentration sensors for direct methanol fuel cells
Liquid-fed direct methanol fuel cells (DMFCs) are one of the most promising candidates for portable power electronics and automotive pplications due to their potentially high-energy density, simple storage, and distribution of the fuel. The concentration of methanol in the fuel irculation loop of a DMFC system is an important operating parameter, because it determines the electrical performance...
