Use the PEM Electrolyzer to produce hydrogen and oxygen using only pure water and an external power source. Take your pick of power sources, all available from Horizon: small solar cell, wind turbines, fuel cells, mechanical hand cranks, or batteries. Using the high-tech proton exchange membrane, this tiny electrolyzer will produce hydrogen for use in any classroom or laboratory activities.

Students will be amazed as they create water and electricity from the hydrogen and oxygen in the air we breathe. The cell obtains its oxygen reactant from the air and by connecting a supply of hydrogen to this device, you will notice a generation of electricity. Comes as a set of five.
