An electrode plate is produced by a wet granule forming process and a film forming process. In the wet granule forming process, wet granules are formed by mixing electrode mixture materials including at least an active material and a binder with a solvent. In the film forming process, a sheet-shaped electrode mixture layer is formed by causing the wet granules to pass through a gap between a pair of rolls so as to be rolled, and the electrode mixture layer is adhered onto a current collector foil. In the wet granule forming process, a powder of copper having an average particle size of 100 nm or smaller is used as one of the electrode mixture materials, and the amount of the powder of copper added in a range of 0.05 wt % to 2.00 wt % with respect to the total weight of the electrode mixture materials.

In polymer electrolyte membrane (PEM) fuel cells and electrolyzes, attaining and maintaining high membrane conductivity and durability is crucial for performance and efficiency. The use of low equivalent weight (EW) perfluorinated ionomers is one of the few options available to improve membrane conductivity. However, excessive dimensional changes of low EW ionomers upon application of wet/dry or freeze/thaw cycles yield catastrophic losses in membrane integrity. Incorporation of ionomers within porous, dimensionally-stable perforated polymer electrolyte membrane substrates provides improved PEM performance and longevity. The present invention provides novel methods using micromolds to fabricate the perforated polymer electrolyte membrane substrates. These novel methods using micromolds create uniform and well-defined pore structures. In addition, these novel methods using micromolds described herein may be used in batch or continuous processing.

A guidance and maintenance machine (100) includes a guide roller (102) and an application roller (104), each having a plurality of respective grooves (102a, 104a) defined on a respective circumferential surface (102b, 104b). The guidance and maintenance machine includes at least one preparation comb (200) having a support (202) with an upper surface (202d) from which a plurality of teeth (204) extend. The teeth, with a predetermined uniform height, are aligned in parallel along a length of the support and are positioned at a pitch between them in correspondence with corresponding grooves (102a) of the guide roller (102) so that the comb (200) feeds filaments (50) from a supply creel (304), where the filaments are stored, to the guide roller (102) at a predetermined pitch positioning outside the guide roller.

The invention is directed to a vehicle pneumatic tire wherein strengthening plies are provided with steel cords running parallel to one another. The belt plies can be used, as isolated electrically conductive plates, for supplying electricity to electrical consumers such as sensors and actuators installed in the tire. Adjacent belt plies can be connected by puncture sensors to be able to identify damage to the belt caused by metallic parts penetrating from the outside, such as nails, on the basis of a change in the electrical resistance.
