NOVELTY - At least partially hydrophobic, porous, electrical conducting, non-woven textile fabric comprises a flocculated and laid matrix of uncoated electrical conducting staple fibers, and electrical conducting particulate filler disposed in the matrix. At least partially hydrophobic polymer in the form of fibrils is disposed in the matrix and at least partially attached to and mixed with the fibers and fillers.    USE - For producing electrochemical apparatus e.g., fuel cell electrode substrate.    ADVANTAGE - The method forms strong non-woven fabric which can be handled in rolled form for shipment, placement and use. The method enables production of a flexible, controllable, continuous, low cost, commercial manufacture of electrical conducting textile fabrics used in gas diffusion electrode substrates as well as a host of other applications. The process is capable of being carried out with existing manufacturing equipment and techniques to form the non-woven textile with excellent electrical, chemical and mechanical properties. The wet laying process maximizes the multi-directional uniform physical properties and electrical conductivity of the fabric and produces a highly active surface area with controlled porosity. Further, uniform flocculation of the suspension can easily be achieved to produce correct flocs by the combination of thermal/mechanical/chemical flocculation. These three means of flocculation can easily control the floc size and thus matrix formation for producing a uniform matrix and ultimately, uniform non-woven textile fabric.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following:    (i) Production of textile fabric which involves:    (a) dispersing staple fibers, particulate filler and suspension of hydrophobic polymer in an aqueous medium to form a suspension,    (b) flocculating the suspension to form flocs,    (c) depositing the flocs on a formaceous body to form a matrix,    (d) de-watering the matrix on formaceous body,    (e) heating the matrix at softening temperature of hydrophobic polymer, and    (f) pressing the matrix at the softening temperature to form fibrils of hydrophobic polymer so that the fibrils are at least partially attached to and mixed with carbon fibers and filler to form a strong, self-supporting textile fabric; and    (ii) Fuel cell which has electrode made of textile fabric.    DESCRIPTION OF DRAWING(S) - The figure shows schematic illustration of textile fabric disposed in fuel cell.    Matrix (2)
