• Oxygen Production Rate: 10 cm³/min @ 1.5 A
• Maximum Permissible Voltage: 4 VDC
• Power Needed: 6 W
• Weight: 2.2 oz (63 g)
• Dimensions (H x W x D): 2.2" x 1.6" x 2.2" (56 x 41 x 56 mm)

About PEM Electrolyzers

The growing significance of PEM electrolyzers mirrors the development of fuel cells. Electrolyzers generate the hydrogen required by fuel cells from water in an environmentally conscious manner. The electrical energy required for this purpose can be gained from renewable sources such as solar cells, wind farms, or hydroelectric plants.

Water reacts in the electrolyzer under the influence of electrical energy according to the following formula: 2H₂O → 2H₂ + O₂. This process takes place in the MEA (membrane electrode assembly). The MEA consists of the cathode, the anode, and a special polymer membrane (PEM) which is permeable to protons but which presents a barrier to electrons. H-TEC electrolyzers function on the PEM principle. The produced gases can be collected in storage tanks (H-TEC Storage 30). The energy stored in chemical form in the gases can be converted back to electrical energy in a fuel cell as and when required.
