SmallSPE/PEM Cell, Diameter only 70mm, very smart!
H2 flow: 0---90ml/min
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 poweron ,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 chamberwith 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

Our Cell Difference with Other Suppliers(Very Important to Read)
1. Diameter:SPE-300/600 diameter: 136mm, bigger than other suppliers. One cell could produce more H2 gas. Inside reaction PEM membrane: 100mm diameter.
Other suppliers inside reaction membrane: 80/85mm diameter.
Small cell: diameter only 7cm, Very smart.
2. Electrode and micropore panel: both use 100% Titanium 1 Metal.
Some suppliers use stainless steel with welding as micropore. Which will corrosion after
Using some time. Some supplier use thin Titanium plate.
We use thickness Titanium 1plate! Which is top level quality grade among Titanium.
3. Mostly Important! Single membrane cell voltage: ours all small than DC 2.5V !
Mostly customer maybe not know this technical data.
it is the directly indication for the cell quality and technical skill. Lower is better!
4. Cell lifetime: As long as use qualified water and proper current.
Our cell average lifetime is 5--8 years, Others is quite shorter
