Isondo lesandla se-valve lizogqwala ngaphansi kwaziphi izimo? Okuyinhloko ukuvimbela ukugqwala kwayo kwamakhemikhali, kodwa ukuvimbela ukugqwala kwayo kwe-electrochemical. Lokhu kudinga ukucabangela ingcindezi, izinga lokushisa, njll. Ngokuvamile, izinto zensimbi zivikelwe ngokudweba, futhi ukubukeka kuhle kakhulu.
