Otu n'ime ụzọ nkwadebe kachasị bụ electrolysis. N'ime cell electrolytic a haziri nke ọma, mmiri na-emebi n'okpuru ọrụ nke ọkụ eletrik. Na cathode, ion hydrogen na-enweta electrons ma ghọọ hydrogen gas. Mmiri hydrogen a na-agbaze na mmiri gbara ya gburugburu, si otú a na-akpụ mmiri hydrogen-ọgaranya. Usoro a dị mfe iji rụọ ọrụ. Ọzọkwa, site n'ịgbanwe ike dị ugbu a na oge electrolysis, a pụrụ ịchịkwa ntinye nke hydrogen na hydrogen - mmiri bara ụba nke ọma. Dịka ọmụmaatụ, ọtụtụ igwe hydrogen - igwe mmiri bara ụba na-ejikarị usoro electrolysis, na-eme ka ndị na-azụ ahịa nwee ike imepụta mmiri bara ụba hydrogen n'oge ọ bụla.
