Ngwá ọrụ electrolysis maka imepụta hydrogen na-adaba n'ụdị isi abụọ: alkaline electrolyzers na proton Exchange membrane (PEM) electrolyzers.
Alkaline Electrolyzers: Ndị a bụ ngwaọrụ dị ogologo na-eji electrolytes mmiri dị ka potassium hydroxide. A maara ha maka ịdịte aka mana ha adịghị arụ ọrụ nke ọma ma e jiri ya tụnyere ndị electrolyzer PEM ọhụrụ.
Proton Exchange Membrane (PEM) Electrolyzers: Oge a na ịrụ ọrụ nke ọma, PEM electrolyzers na-eji akpụkpọ anụ polymer siri ike kewaa mmiri n'ime hydrogen na oxygen. Ha na-arụ ọrụ na obere okpomọkụ ma na-enye oge nzaghachi ngwa ngwa.
Ihe ndị dị mkpa gụnyere electrodes, electrolyte (mmiri maka alkaline, polymer siri ike maka PEM), ọkụ ọkụ (site na isi mmalite ma ọ bụ grid), usoro nkewa gas, na ngalaba njikwa maka ọrụ nchekwa.
Mgbe ị na-ahọrọ ngwá ọrụ electrolysis, tụlee arụmọrụ, ọnụ ahịa, scalability, mkpa mmezi, na ngwa a chọrọ (ụlọ ọrụ, azụmahịa, ma ọ bụ ebe obibi). Ọganihu na-aga n'ihu na-achọ ịkwalite arụmọrụ, ọnụ ahịa dị ala, yana gbasaa oke ngwa hydrogen.
Ngwa Electrolysis maka mmepụta hydrogen gụnyere: electrode-diaphragm mgbakọ maka alkaline mmiri electrolysis,Polymer electrolyte akpụkpọ anụ (pem) electrolyzers,nel alkaline electrolyser,ion membran electrolyzer.
