H2 Gas Generation by Water Electrolyses

Product Introduction

 

SPE series Water Electrolyzer are advanced technology, which are light, highly effective, energy-saving and of environmental protection , producing extremely pure hydrogen through the electrolysis of pure water (without adding alkali).

The SPE electrodes, as the core of the product, are highly active catalytic electrode with nearly zero distance between the electrodes, which is formed by integrating composite catalyst with and ion membrane with high electrolytic efficiency. The other key parts are all produced by use of top-grade engineering plastics dies with superior quality. With perfect electric control system, designs of the generators are advanced with reliable quality, high automation, extremely pure generated hydrogen, huge output, the models and specifications of the generators are complete, and the generators are idly used.

 

Operational Principle

 

Water Electrolyses meeting the requirements (With electrical resistivity >1MΩ/ cm, and deionised or Redistilled water in electronic and analysis industries can be used for this purpose.) , after being put into the anode chamber of electrolytic cell, when power is switched on ,will be decomposed at once at the anode : 2H2 O = 4H++ 2O-2. The decomposed negative oxy anion (O-2) will immediately release electron to form oxygen (O2), which will then be discharged from the anode chamber, with some water, into the water tank. The water can be used circularly, and oxygen will be discharged from the small hole of the top cover of the water tank into the atmosphere. The hydrogen proton, in the form of aqua ion (H+·XH2 O), and under the action of electric field force, through SPE ion membrane, will arrive in the cathode to absorb electron to form hydrogen, which will then be discharged from the cathode chamber into the gas/water separator, where most of water it brought with from the lectrolytic cell will be removed. The hydrogen with little water will be under moisture absorption of the desiccators, with its purity thus reaching 99.999 % or above.

 

SPE/PEM Technology Advantages

 

  • SPE technology---Solid Polymer Electrolyte
  • The SPE electrodes, as the core of the product, are highly active catalytic electrode with nearly zero distance between the electrodes, which is formed by integrating composite catalyst with ion membrane with high electrolytic efficiency.
  • Plural-electrode and multiunit electrolysis cell structure. Excellent chemical technological process properties of heat and mass transfer,
  • . Electrolysis of pure water (no adding alkali) to produce high purity (99.999%/99.9995%) hydrogen with no corrosion and pollution.
  • Voltage of cell is low, electronic resistance in the electrolysis cell is little, could greatly saving energy. Circle time for changing desiccants is long.
  • Power consumption is less, electrolysis is efficient
