Indlela yokusebenzisa impande yediski ye-graphite
Izivalo eziwusizo zamaphampu nama-valve zincike esimweni sonke sengxenye ngayinye, ikakhulukazi idivayisi yediski ye-graphite kanye nokulungiswa kwayo. Ngaphambi kwedivayisi yokugoqa, kholelwa ngokuqinile ukuthi isidingo semishini yokugoqa ye-graphite eyengeziwe besihambisana nendawo kanye nohlelo lokuhlukanisa okuwusizo...Funda kabanzi -
Ukuhlaziywa kwezomnotho kokukhiqizwa kwe-hydrogen eluhlaza nge-electrolysis evela emithonjeni yamandla avuselelekayo
Amazwe amaningi aqala ukubeka imigomo yamasu yamandla e-hydrogen, kanti ezinye izimali zihlose ukuthuthukiswa kobuchwepheshe be-hydrogen obuluhlaza. I-EU ne-China zihola le ntuthuko, zifuna izinzuzo zokuqala kwezobuchwepheshe kanye nengqalasizinda. Okwamanje, iJapan, iNingizimu ...Funda kabanzi -
Inqubekela phambili kanye nokuhlaziywa kwezomnotho kokukhiqizwa kwe-hydrogen nge-electrolysis yama-oxide aqinile
Inqubekela phambili kanye nokuhlaziywa kwezomnotho kokukhiqizwa kwe-hydrogen nge-electrolysis yama-solid oxides I-Solid oxide electrolyzer (SOE) isebenzisa umhwamuko wamanzi okushisa okuphezulu (600 ~ 900°C) ekuhlaziyweni kwe-electrolysis, okusebenza kahle kakhulu kune-alkaline electrolyzer kanye ne-PEM electrolyzer. Ngawo-1960, i-United States kanye neJalimane...Funda kabanzi -
I-hydrogen yamazwe ngamazwe | I-BP ikhiphe "umbono wamandla omhlaba" ka-2023
Ngomhlaka-30 Januwari, iBritish Petroleum (BP) yakhipha umbiko we-“World Energy Outlook” ka-2023, igcizelela ukuthi uphethiloli wezinto ezisetshenziswayo esikhathini esifushane ubaluleke kakhulu ekushintsheni kwamandla, kodwa ukushoda kwamandla emhlabeni wonke, ukukhishwa kwekhabhoni kuyaqhubeka nokwanda kanye nezinye izinto ezilindelekile...Funda kabanzi -
Inqubekela phambili kanye nokuhlaziywa kwezomnotho kwe-hydroelectrolysis ye-ion exchange membrane (AEM) yokukhiqizwa kwe-hydrogen
I-AEM ngezinga elithile iyinhlanganisela ye-PEM kanye ne-electrolysis yendabuko esekelwe ku-diaphragm. Isimiso se-AEM electrolytic cell siboniswe kuMfanekiso 3. Ku-cathode, amanzi ayancishiswa ukuze akhiqize i-hydrogen kanye ne-OH -. OH - egeleza nge-diaphragm iye ku-anode, lapho ihlangana khona ukuze ikhiqize i-o...Funda kabanzi
