摘要： Methods for the conversion of a biofuel such as biodiesel into an alkane composition such as an aviation fuel, kerosine, or liquified petroleum gas product involve a series of electrochemical reactions. The reactions include oxidation of methanol to carbon dioxide, reduction of fatty acid esters, and cleavage of fatty acid chains at C═C double bonds. The methods are carried out by systems of two or more electrochemical reactors.

摘要： A catalyst for use in at the anode of direct methanol fuel cells is made from nanoparticles having a core-shell structure. The core is an alloy of platinum and gold. The core is surrounded by a first shell of ruthenium and a second shell containing a ternary alloy of platinum, gold, and ruthenium. The catalyst can be made by a reverse-micelle method or by a single-phase scalable method. The catalyst is highly stable under conditions of use and resists dissolution of ruthenium or platinum.

摘要： A process for the highly efficient oxidation of ethanol in fuel cells involves the addition of a metal co-catalyst oxidation enhancer to the fuel cell electrolyte in soluble form. The enhancer vastly improves the rate of ethanol ethanol oxidation and promotes oxidation of the C—C bond to CO2. The metal co-catalyst can adopt oxidation number II and oxidation number IV and forms a redox couple that promotes oxidation reactions at the anode. Embodiments of the invention include fuel cells, methods of their operation, and fuel cell electrolyte solutions for the efficient electro-oxidation of organic fuels including ethanol.

摘要： Water soluble catalysts, (M)meso-tetra(N-Methyl-4-Pyridyl)Porphinepentachloride (M=Fe, Co, Mn & Cu), have been incorporated into the polymer binder of oxygen reduction cathodes in membrane electrode assemblies used in PEM fuel cells and found to support encouragingly high current densities. The voltages achieved are low compared to commercial platinum catalysts but entirely consistent with the behavior observed in electroanalytical measurements of the homogeneous catalysts. A model of the dynamics of the electrode action has been developed and validated and this allows the MEA electrodes to be optimized for any chemistry that has been demonstrated in solution. It has been shown that improvements to the performance will come from modifications to the structure of the catalyst combined with optimization of the electrode structure and a well-founded pathway to practical non-platinum group metal catalysts exists.
