Abstract
The invention relates to a current collector for electrochemical diaphragm or membrane-type cells, comprising a layer obtained by interlacing or weaving of a multiplicity of first sets of metal wires with a multiplicity of single metal wires or of second sets of metal wires and provided with substantially parallel corrugations. Such layer is coupled to a planar element consisting of a cloth or a flattened stocking formed by weaving of a single metal wire. The current collector is characterised by a low angular coefficient of the pressure/thickness ratio over a wide range of compression levels.
