Why Dimensionally Stable Anodes(DSAs) Are Used for Zinc Electrowinning? Zinc electrowinning is one of the basic processes of the electrochemical industry. Lead-silver anodes have been used in zinc production for years. Although these electrodes have the lowest current efficiency for zinc deposition and higher electrical energy consumption when compared to pure lead anodes, they are widely used because of their high corrosion stability in acid (H2SO4) solution and because of the higher purity of the zinc cathodic deposits. In se

How Dimensionally Stable Anode(DSA) is Used in Hydrogen Production? Carbon emission from carbon-based fuels causes environmental problems, while hydrogen is regarded as a new energy source to replace fossil fuels. The production and storage of hydrogen have become essential technologies recently. Electrolysis of water using electricity or sunlight is the method that is being used for the environmentally benign production of hydrogen. However, hydrogen production through electrolysis is hindered by the slow oxygen evolution reaction

Detailed Explanation About Impressed Current Anodes for Buried Concrete Structures Galvanic Anodes For buried concrete structures, traditional galvanic anodes based on zinc or magnesium may be used. The required minimum net mass of the anodes is determined from the total current requirement, anode alloy capacity, design life and anode utilization factor. The size and number of anodes is also determined from the anode current output, which in turn is based on anode shape, soil resistivity and anode operating potential. For high-res

How Impressed Current Anodes Are Used for Immersed Concrete Structures? Both Galvanic anodes and Impressed current anodes are applied for immersed concrete structure cathodic protections. However, there are some differences between these two types of anodes. Galvanic Anodes Galvanic anodes for immersed structures will normally be slender stand-off or hull-mounted type anodes and will normally be installed by direct welding of the anode steel core to the embedded steel. This will require breakout of the concrete to expose embedd
