Palladium-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 کاملIV.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 کاملFunctionalized and Electrospun Polymeric Materials as High-Performance Membranes for Direct Methanol Fuel Cell: A Review
Proton exchange membranes (PEM) for a direct methanol fuel cell (DMFC) have main drawbacks which are methanol permeability, reduced proton conductivity and the cost of the membrane. This paper reviews different polymeric materials such as fluorinated, non-fluorinated, acid-base complex, and composite membranes for DMFC. Currently, nonfluorinated membranes gain a lot of atte...
متن کاملSupport Effects on Palladium Catalysts for Methanol Fuel Applications
Methanol, formaldehyde, carbon monoxide, and propylene conversion were examined in a laboratory flow reactor over three base-metal containing alumina-supported palladium (Pd) catalysts in addition to Pd on y-alumina catalyst. The base metals were cerium, barium, and a combination of the two. Experiments were performed to determine the effect of air to fuel ratio on lightoff temperatures of vari...
