Web10 okt. 2024 · Membrane cell The most common chloralkali process involves the electrolysis of aqueous sodium chloride (a brine) in a membrane cell. A membrane, … WebA membrane cell is a diaphragm cell with an improved diaphragm called a ‘membrane’. This is made from polytetrafluoroethylene (PTFE), making it a plastic membrane, which has been modified to include anionic groups to act as an ion exchange membrane. This allows sodium ions to pass through it but not chloride or hydroxide ions.
WebUsing solar energy to electrochemically split water into oxygen and hydrogen, akin to how plants photosynthesise, shows much promise for renewable energy. The hydrogen that’s liberated can then be mixed with carbon dioxide to make hydrogen fuels.
