Wani binciken da ke hanzarta tallan ƙwayoyin sel masu ƙarfi na oxide don samar da koren hydrogen

Fasahar samar da koren hydrogen yana da matuƙar zama dole don a samu fahimtar tattalin arzikin hydrogen domin, ba kamar hydrogen mai launin toka ba, koren hydrogen ba ya samar da iskar carbon dioxide mai yawa yayin samarwa.
