Amazwe amaningi azibophezele emigomweni yokukhipha ugesi ongenayo igesi eminyakeni eyishumi ezayo. I-hydrogen iyadingeka ukuze kufinyelelwe le migomo ejulile yokususa ugesi ongcolile. Kulinganiselwa ukuthi u-30% wokukhishwa kwe-CO2 okuhlobene namandla kunzima ukuwuqeda ngogesi kuphela, okunikeza ithuba elikhulu le-hydrogen. Iseli likaphethiloli lisebenzisa amandla amakhemikhali e-hydrogen noma amanye amafutha ukuze likhiqize ugesi ngendlela ehlanzekile nephumelelayo. Uma i-hydrogen inguphethiloli, imikhiqizo kuphela ugesi, amanzi, nokushisa.Amaseli kaphethilolizihlukile ngokwezinhlobonhlobo zezicelo zazo ezingaba khona; zingasebenzisa uphethiloli ohlukahlukene kanye nezitsha zokudla futhi zinganikeza amandla ezinhlelweni ezinkulu njengesiteshi sikagesi esisetshenziswayo kanye nezincane njengekhompyutha ephathekayo.
Iseli likaphethiloli liyiseli le-electrochemical eliguqula amandla amakhemikhali kaphethiloli (ngokuvamile i-hydrogen) kanye ne-oxidizing agent (ngokuvamile i-oxygen) abe ugesi ngokusebenzisa ukusabela kwe-redox okubili. Amaseli kaphethiloli ahlukile kumabhethri amaningi ngokudinga umthombo oqhubekayo kaphethiloli kanye ne-oxygen (ngokuvamile evela emoyeni) ukuze aqhubeke nokusabela kwamakhemikhali, kanti ebhethrini amandla amakhemikhali avame ukuvela ezinsimbini kanye nama-ion noma ama-oxide azo [3] avame ukuba khona kakade ebhethrini, ngaphandle kwamabhethri okugeleza. Amaseli kaphethiloli angakhiqiza ugesi ngokuqhubekayo inqobo nje uma uphethiloli kanye ne-oxygen kunikezwa.
Enye yezingxenye eziyinhloko zeseli likaphethiloli le-hydrogen yi-i-graphite ipuleti le-bipolarNgo-2015, i-VET yangena embonini yamaseli kaphethiloli ngezinzuzo zayo zokukhiqiza amapuleti e-electrode kaphethiloli we-graphite. Yasungula inkampani iMiami Advanced Material Technology Co., LTD.
Ngemva kweminyaka eminingi yocwaningo nentuthuko, udokotela wezilwane unobuchwepheshe obuvuthiwe bokukhiqiza i-10w-6000wAmaseli kaphethiloli e-hydrogen. Amaseli kaphethiloli angaphezu kuka-10000w asebenza ngezimoto ayathuthukiswa ukuze afake isandla ekongiweni kwamandla kanye nokuvikelwa kwemvelo. Ngokuphathelene nenkinga enkulu yokugcina amandla yamandla amasha, sibeka umbono wokuthi i-PEM iguqula amandla kagesi abe yi-hydrogen ukuze igcinwe futhi amaseli kaphethiloli e-hydrogen akhiqiza ugesi nge-hydrogen. Ingaxhunyaniswa nokukhiqizwa kwamandla e-photovoltaic kanye nokukhiqizwa kwamandla e-hydropower.
