SPE/PEM Cell General Introduction:

   SPE/PEM technology electrolysis cell, use world advanced Proton Exchange Membrane technology, only use little electricity and pure water, to produce pure hydrogen gas. No need to add KOH. We mainly produce five types now, round shape cell have: SPE-90 small cell with H2 flow 0--90ml/min, SPE-300: H2 flow 0--300ml/min and SPE-600:0--600ml/min. SPE-1200plus  round type and SPE-2000plus round cell. Square shape cell have: SPE-600plus: 0--600ml/min, SPE-1200plus: 0--1200ml/min and SPE-2000plus with H2 flow 0--2000ml/min. It is widely be used in Hydrogen generator, people breath and rich hydrogen water to drink etc. 

Working Principle:

when power on ,water will be decomposed at once at the anode : 2H₂ O = 4H⁺ + 2O^-2. The decomposed negative oxyanion (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, oxygen will be discharged 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
