The bottle contains a base with electrodes (usually platinum-coated titanium) and a Solid Polymer Electrolyte (SPE) or Proton Exchange Membrane (PEM). When you turn it on: Electrolysis: An electric current splits water molecules (H_2O) into hydrogen gas and oxygen. * Infusion: The hydrogen gas is dissolved into the water. Venting: High-quality bottles (using SPE/PEM technology) vent out byproducts like ozone and chlorine so only pure H_2 remains in your drink. Potential Health Benefits
