摘要： It is described a bipolar plate consisting of a single wall and a perimetrical sealing frame obtained by folding and provided with a planar abutment surface for the frame-to-wall welding. The wall is further provided with projections on one face thereof preferably obtained by moulding, and with supports on the other face consisting of sheet strips housed in the recesses formed by the concave part of the projections. The projections substantially extend along the entire length of the bipolar plate. The projections and supports are connected to electrodes or current distributors. The projections, the supports, the single wall and the perimetrical frame are made of the same metal or alloy. The electrode or current distributor supported by the projections, the same projections and the supports are welded together by a single pass of arc-welding or preferably laser-welding. The electrode or current distributor connected to the support and the support themselves are mutually welded by a subsequent pass of arc-welding or preferably laser-welding. The welding between wall and perimetrical frame on the abutment surface of the frame is carried out by diode-laser technique, allowing to obtain a robust connection but without a complete melting of the sheet, thereby eliminating the risk of process fluid leakage to the external environment.

摘要： A bipolar assembly for filter-press type electrolyzers is described comprising a single sheet, whose two faces work respectively as anodic and cathodic wall, characterised by a design of perimetral flanges which greatly simplifies its construction enhancing its reliability. The peripheral flanges are made of a first flange obtained by folding the peripheral portion of the single sheet and of a second flange formed by a rod or a tube with quadrangular section or, alternatively, the first and second flange are pre-formed by folding of adequate strips subsequently fixed to the single sheet. The electrolyser resulting from the assemblage of a multiplicity of assemblies of the invention is particularly suited to the process of electrolysis of hydrochloric acid solutions carried out with chlorine-evolving anodes and oxygen-consuming cathodes.

摘要： Bipolar plate made of a composite material for use in a filter-press electrolyzer. Said plate comprises a central portion (6) which is electrically conductive and is obtained by heat-pressing of a mixture of graphite or conductive carbon and a thermoplastic polymer powder resistance to corrosion and two terminal portions (7,8) containing the distribution holes (2,3,4,5) for the inlet of the fresh electrolytes and for the outlet of the exhausted electrolytes and electrolysis products. Said terminal portions are integral with the central portion and are obtained during said heat-pressing from a mixture of graphite or conductive carbon and said thermoplastic polymer powder with a ratio between said powders lower than that of the central portion. Said mixture of the terminal portions may further contain also a non-conductive compound powder, in which case the mixture may also be free from graphite or conductive carbon powder.

摘要： A membrane electrolysis cell comprising an anodic compartment and a cathodic compartment is described, wherein at least one of the two compartments contains an electrode fed with gas and a porous planar element is interposed between the membrane and the gas-fed electrode. A flow of chemically aggressive electrolyte crosses the porous planar element downwards under the effect of the gravity force. The planar element consists in a plastic element withstanding the aggressive operative conditions: The use of perfluorinated plastics such as ECTFE, PTEFE, FEP, PFA is preferred, even though they are strongly hydrophobic. When the gas-fed electrode is a cathode and the gas contains oxygen, the gas crosses the cathodic compartment upwardly so as to minimize the risk of hydrogen build up. The cell equipped with the oxygen cathode is particularly advantageous for the sodium chloride electrolysis.
