Abstract:

Electrodes for polymer electrolyte membrane and direct methanol fuel cells comprise carbon nanotubes and catalytically active metal. In one embodiment, anode electrodes are prepared by depositing catalytic metal on carbon nanotubes, and forming the carbon nanotubes into a membrane. Anode electrodes comprising carbon nanotubes provide higher fuel cell performance with a much lower platinum loading than conventional carbon-based electrode material having a much higher platinum loading. In another embodiment, a catalyst ink comprising carbon nanotubes and a catalytic metal-loaded carbon powder was used to form an electrode membrane. The catalyst ink comprising carbon nanotubes and catalyst-loaded carbon powder can optionally comprise an ionically conductive polymer, such as a perfluorosulfonic acid/PTFE copolymer. In another embodiment, a fuel cell electrode comprising carbon nanotubes and catalytically active metal is a free-standing electrode. In another embodiment of a membrane electrode assembly, carbon nanotubes are sandwiched between a catalyst-loaded electrode and a polymer electrolyte membrane.

Abstract:

This disclosure describes a novel method for predicting or estimating rock mechanical properties from cuttings at a particular depth based on determining the facies, plotting the facies on a ternary diagram with clay, silica and carbonate endpoints, and estimating rock mechanical properties based on comparison to a database of core samples from vertical wells that is also organized by depth and facies. We have shown that datapoints at similar locations on the ternary diagram will have fairly similar rock properties. These rock properties can be used to improve the reliability of a variety of reservoir modeling platforms, which can then be used in designing and implementing completion, stimulation and production plans.
