A glass fiber-based paper diffusion medium, as well as a membrane humidifier for a fuel cell and method for humidifying a fuel cell using the provided glass fiber-based paper diffusion medium. The diffusion medium is a flexible, resin-bonded glass fiber paper impregnated with 26-55% cured liquid phenolic resin and having a thickness of 100-110 &#x3bc;m and a Gurley permeability of at least 100 cfm.

Wet side paper for fuel cell humidifier

A fuel cell comprises a cathode gas diffusion layer, a cathode catalyst layer, an anode gas diffusion layer, an anode catalyst layer and an electrolyte. The diffusion resistance of the anode gas diffusion layer when operated with anode fuel is higher than the diffusion resistance of the cathode gas diffusion layer. The anode gas diffusion layer may comprise filler particles having in-plane platelet geometries and be made of lower cost materials and manufacturing processes than currently available commercial carbon fiber substrates. The diffusion resistance difference between the anode gas diffusion layer and the cathode gas diffusion layer may allow for passive water balance control.

Low cost fuel cell diffusion layer configured for optimized anode water management

A water-resistant composite paper, suitable for use as a loudspeaker component, is made from a composition including wood pulp, hydrophobic fibers, and stiffening fibers that retain stiffness when wet. In some examples, fibrillated acrylic fibers and glass fibers are used.

Waterproofing loudspeaker cones

An automobile or like power operated radio antenna comprising a telescopic mast tube assembly fabricated of tough flexible polymeric material in tubular sections enclosing an inner metallic drive cable of helically coiled wire serving not only as the actuating cable for deployment of the antenna to and from an extended position but also as the conductive radio wave collector element.
