Compositions and methods for the manufacture of electrodes for fuel cells. The compositions and methods are particularly useful for the manufacture of anodes and cathodes for proton exchange membrane fuel cells, particularly direct methanol fuel cells. The methods can utilize direct-write tools to deposit ink compositions and form functional layers of a membrane electrode assembly having controlled properties and enhanced performance.

Method of producing membrane electrode assemblies for use in proton exchange membrane and direct methanol fuel cells

An electrocatalyst ink composition comprising a liquid vehicle, particles comprising at least one electrocatalyst metal, and at least one copolymer dispersant comprising at least one polyalkylene oxide segment.

Electrocatalyst inks for fuel cell applications

A method for forming an electrically isolated via in a multilayer ceramic package and an electrical connection formed within the via are disclosed. The method includes punching a first via in a first layer, filling the first via with a cross-linkable paste, curing the paste to form an electrical insulator precursor and forming the via in the insulator precursor. The electrical connection formed includes an insulator made from a cross-linked paste supported by a substrate of a multilayer ceramic package and a conductive connection supported by the insulator.

Multiphase ceramic materials for use in multilayered device fabrication may be fabricated by providing novel glassy precursor materials of a preferred composition, with operable amounts of a non-glassy filler materials. The combined materials are fired at appropriate temperatures, so that a non-glassy anorthite type phase is formed. Material so fabricated is formed in a self-limiting process, in that reaction between the glassy precursor material and the non-glass filler material is terminated when one constituent of the glassy precursor material is fully consumed. The materials of the instant invention, fabricated according to the method disclosed herein, demonstrate excellent dielectric constant, and electrical loss characteristics.

Ceramic composition and method of making same

A method of producing a glass/metal package where a glass portion of the package is built up around a provided leadframe (10) using applications of solderable and glass pastes (20) which are subsequently fired (30). The glass paste and leadframe are chosen to have similar coefficients of expansion and the leadframe is pretreated to degasify and control oxidation of the metal to promote glass adhesion to the leadframe and prevent microcracking at a glass/metal interface. A seal ring is applied to the glass paste (40) and a lid is attached to the seal ring (50). The package is used to provide an sealed inert internal environment for sensitive electronic components such as a piezoelectric element. The package may be configured for leaded or surface mounting (60).
