WebElektroliza vode se koristi pretežno za dobivanje vodika. Voda koja se koristi ne smije biti destilirana (jer takva voda ne provodi električnu struju ), pa se u nju često dodaje malo kuhinjske soli. Elektrode moraju biti napravljene od platine jer bi nastali kisik reagirao s većinom ostalih metala.
