摘要： A process for the activation of a membrane electrode assembly, such as a direct methanol fuel cell membrane electrode assembly, with a hydrocarbon fuel, e.g., an alkanol fuel such as methanol, and an oxidant is described. The process comprises repeatedly applying an increasing or decreasing potential in each of a plurality of cycles over a voltage range of at least 0.1 volts, e.g., at least 0.2 volts or at least 0.3 volts, until the membrane electrode assembly is substantially activated. The cycles optionally are organized in cycle sets with rest periods therebetween. The temperature at which the cycles are run optionally is increased or decreased in a respective cycle set.

摘要： A composite material having utility for removing sulfur from a feedstock comprises a ceramic matrix having a relatively low melting point metal such as tin, zinc, lead or bismuth nanodispersed therein. The material may be prepared from a mixture of particles of a precursor of the ceramic matrix and precursor of the metal. The precursors are selected such that the melting point of the precursor of the ceramic is less than the melting point of the precursor of the metal. The mixture of precursor materials is heated to a temperature sufficient to melt the precursor of the ceramic material so as to coat it onto the precursor of the metal. The ceramic precursor is then reacted so as to convert it to a ceramic. Thereafter, the precursor of the metal is converted to a free metal which is retained within the ceramic matrix so as to prevent agglomeration.

摘要： A catalyst is synthesized by a method in which a catalytic metal such as platinum or another noble metal is dispersed onto a support member. A transition metal macrocycle is also adsorbed onto the support, and the support is heat treated so as to at least partially pyrolyze the macrocycle and anchor the transition metal to the support. The catalytic metal is alloyed with the transition metal either during the pyrolysis step, or in a separate step. The catalyst has significant utility in a variety of applications including use as an oxygen reduction catalyst in fuel cells.
