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 three types now, SPE-90 small cell with H2 flow 0--90ml/min, SPE-300 with H2 flow rate 0--300ml/min and SPE-600 with H2 flow rate 0--600ml/min. It is widely be used in Hydrogen generator, people breath and rich hydrogen water to drink etc.
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
SPE-90 cell, diameter only 7cm, H2 flow rate: 0--90ml/min, PEM technology.
