A method is provided for coating a fibrous web, in particular a fibrous web comprising nanocellulose fibres. The method includes steps of applying a coating agent to a textured surface region of a textured substrate, applying a fibre furnish or a wet fibrous web onto the coated textured surface region of the textured substrate, optionally dewatering to provide a wet fibrous web, and drying said wet fibrous web such that at least a portion of said coating agent is transferred to said fibrous web. The method provides a coated fibrous web with improved barrier properties.

Provided is a porous electrode substrate capable of reducing a drop in electromotive force when used in a battery. This porous electrode substrate comprises a carbon fiber sheet wherein carbon fibers are bound by a binder. For dust of 0.3 μm or more in particle size, the dust generation amount per 1 m.sup.2 of the porous electrode substrate is 120,000/m.sup.2 or less, as determined by the following method: dust particles in a gas obtained by suctioning at 47.2 mL/s for 40 minutes using a dust collecting hood having an opening of 500 mm×100 mm while traveling the sheet at a speed of 10 m/min from a position 200 mm below the sheet are used; the number of dust particles having a diameter within a predetermined range is measured by a particle counter; and the measured value is divided by 200 m.sup.2, which is a suction area, and the resulting value is defined as a dust generation amount per 1 m.sup.2.
