A solid polymer electrolyte membrane having (a) an ion exchange material and (b) dispersed in said ion exchange material, a hydrogen peroxide decomposition catalyst bound to a carbon particle support, wherein the hydrogen peroxide decomposition catalyst comprises (i) polyvinylphosphonic acid and (ii) transition metal with multiple oxidation states or a lanthanide metal with multiple oxidation states.

Highly stable fuel cell membranes and methods of making them

A solid polymer electrolyte membrane having (a) an ion exchange material and (b) dispersed in said ion exchange material, a hydrogen peroxide decomposition catalyst bound to a carbon particle support, wherein the hydrogen peroxide decomposition catalyst comprises (i) polyvinylphosphonic acid and (ii) cerium.

An improved optical signal transmission media comprises at least one light-transmitting fiber core defined by a cladded optical fiber, and a buffering surrounding the light transmitting fiber core. The buffering is defined by a closed-cell porous polymer material.

Buffer material for optical signal transmission media

A combined sensing and barrier element is provided. This sensing element is most useful as a flexible diaphragm which is also described herein. The flexible diaphragm has a resilient elastomeric body and a sensing element having at least one conductive component and at least two nonconductive components such that the conductive component is positioned between the nonconductive components. A change in electrical resistance is recorded by an electrical monitoring device that is electrically connected to the conductive component. By observing changes in the resistance that deviate from a predetermined norm, significant wear of a diaphragm can be determined prior to its failure.

Pre-failure sensing diaphragm

This invention provides a densified previously expanded PTFE article having remnants of a fibril and node structure and a process for producing the article. A PTFE shape is compressed through the application of heat and pressure while the shape itself is under a vacuum, thus forming the densified ePTFE article. The densified PTFE article exhibits increased flexural strength. A diaphragm containing the densified ePTFE article as one layer is also disclosed.

Dense polytetrafluoroethylene articles

A flexible pump diaphragm for pumping fluids is described in which the diaphragm has a number of ribs or troughs located radially across its circumferential flexure portion.
