Water Electrolyzer of Bangladesh, Electrolysis of water is the decomposition of water (H2O) into oxygen (O2) and hydrogen gas (H2) due to an electric current being passed through the water.
Principle of Water Electrolyzer: A DC electrical power source is connected to two electrodes, or two plates (typically made from some inert metal such as platinum, stainless steel or iridium) which are placed in the water. Hydrogen will appear at the cathode (the negative electrode, where electrons enter the water), and oxygen will appear at the anode (the positive electrode). Assuming ideal faradaic efficiency, the amount of hydrogen generated is twice the amount of oxygen, and both are proportional to the total electrical charge conducted by the solution. However, in many cells competing side reactions occur, resulting in different products and less than ideal faradaic efficiency.
Electrolysis of pure water requires excess energy in the form of over potential to overcome various activation barriers. Without the excess energy the electrolysis of pure water occurs very slowly or not at all. This is in part due to the limited self-ionization of water. Pure water has an electrical conductivity about one millionth that of seawater. Many electrolytic cells may also lack the requisite electro catalysts. The efficiency of electrolysis is increased through the addition of an electrolyte (such as a salt, an acid or a base) and the use of electro catalysts.
Currently the electrolytic process is rarely used in industrial applications since hydrogen can currently be produced more affordably from fossil fuels.

Testing methods of Water Electrolyzer:Prepare for water—using white glass with 100-500ml water capacity,one glass is filled in running water and the other glass is filled in RO pure water, put them in the table side by side Prepare for testing—put the electrolyzer in the glass , then insert to the power Testing—turn on the button “on”, and test for 30 seconds, then turn on the “off”, remove the water electrolyzer.
