Description
H-TEC Education's 1-Cell Rebuildable PEM Electrolyzer Kit contains a Proton Exchange Membrane ElectrolyZer (PEMEZ) that can be completely disassembled and then reassembled especially for education and research purposes. The PEM electrolyzer can generate hydrogen and oxygen from deionized water (or distilled water) with the aid of a power supply. This education kit is ideal for students to learn about hydrogen economy and clean energy technologies. All the tools needed for assembly/disassembly of the 1-cell hardware are included! A power supply is not included in the education kit. A small and simple power supply that can provide the following voltage and current values will be sufficient to operate this electrolyzer cell: 0 V to 2.5 V and 0 A to 5 A.
In an electrolyzer, electrical energy is converted directly to chemical energy via an electrochemical process. Deionized water (or distilled water) is supplied from outside to the anode side of the electrolyzer cell and gets converted into hydrogen and oxygen gas. This is also known as electrolysis. In the electrolysis reaction, at the anode side, deionized water (or distilled water) is converted into protons, oxygen gas, and electrons. Protons travel to the cathode side by going through the membrane used inside the electrolyzer cell. Electrons travel to the cathode through the external circuit. At the cathode, protons are reduced to hydrogen gas.

The provided electrolyzer performance data is only for reference purposes. Depending on the quality of the deionized water, temperature of the water, ambient temperature, water transfer method (actively fed with a liquid pump or gravity-fed), etc., customers may get slightly lower or higher performance than the ones posted for this particular product.
