The support frame (7) describes a step shape having two adjacent cross-sectional areas (12, 13), in which the edge (18) of the membrane (6) lies in a step (17) formed by the cross-sectional areas (12, 13) and the porous transport layer (10) of the half-cell (3) extends into the step (17), and in which the porous transport layer (10) of the half-cell (3) extends into the step (17). According to the invention, the support frame (7) comprises at least one sealing arrangement (15) injection molded onto the support frame (7) and comprising an electrically insulating sealing material, according to the invention, the sealing arrangement (15) comprises three sealing regions (19, 20, 21), each having at least one sealing lip (22, 22 '), in particular a first sealing region (19) and a second sealing region (20) and a third sealing region (21), which are assigned to narrower regions of the two cross-sectional regions (12, 13) facing the membrane (6), the first sealing region and the second sealing region each contact exactly one bipolar plate (5, 5 '), and the third sealing region is located on a side of the support frame (7) facing away from the step (17)

A SYSTEM FOR REGENERATION OF ELECTROLYTES OF AN ALL-IRON FLOW BATTERY

Resumen de: UA129667C2

The invention relates to the energy industry and concerns an iron-iron flow battery system, which implements the process of electrolyte regeneration by introducing into the positive electrolyte circuit of an iron-hydrogen battery powered by hydrogen produced during charging at the negative electrode of an iron-iron flow battery, and Fe3+ ions generated during charging at its positive electrode, and a flow iron-oxygen electrolyzer, which uses the current generated by the flow iron-hydrogen battery to reduce Fe3+ ions in the negative electrolyte and generate hydrogen protons to restore its acidity. As a result, the system reduces the excess Fe3+ released on the positive electrode to Fe2+ in the positive electrolyte, maintains a stable pH value in the negative electrolyte, and reduces the Fe3+ ions in the negative electrolyte that pass from the positive electrolyte through the membrane to Fe2+ ions, thereby reducing corrosion of the negative electrode. The invention ensures elimination of the imbalance in the degree of charge of the positive and negative electrolytes. 28

A METHOD FOR REGENERATING ELECTROLYTES OF AN ALL-IRON FLOW BATTERY

Resumen de: UA129666C2

The invention belongs to the energy industry and relates to a method of regenerating electrolytes in an iron-iron flow battery system by introducing into the positive electrolyte circuit of an iron-hydrogen battery powered by hydrogen produced during charging at the negative electrode of the iron-iron battery, and Fe3+ ions formed during charging on its positive electrode, and an iron-oxygen electrolyzer, which, using the current received from the operation of the iron-hydrogen battery, restores Fe3+ ions in the negative electrolyte and generates hydrogen protons to restore its acidity. As a result of this implementation of the method, excess Fe3+ released at the positive electrode is reduced to Fe2+ in the positive electrolyte, a stable pH value is maintained in the negative electrolyte, and Fe3+ ions passing from the positive electrolyte through the membrane are reduced in the negative electrolyte to Fe2+ ions, thereby reducing corrosion of the negative electrode. The invention ensures elimination of the imbalance in the degree of charge of the positive and negative electrolytes.

Resumen de: DK202430381A1

In a method of producing electrodes (20), for example for fuel cells, two aqueous coatings (15, 16) are subsequently applied onto a porous hydrophobic electroconductive substrate (10). A first coating containing a sacrificial hydrophilic polymer, for example HEC and/or PPC, is applied for temporarily hydrophilizing the substrate surface. For providing a catalyst layer, CL, a second coating is applied on the first coating. The second coating comprises an electroconductive filler and a catalyst and water soluble polymeric binders, for example PVA and HPC. By heating the coatings, the sacrificial polymer decomposes and evaporates and binds the catalyst layer to the substrate.
