Njengamanje, amazwe amaningi azungeze zonke izici zocwaningo olusha lwe-hydrogen aseguquguqukayo, ubunzima bezobuchwepheshe ekukhuphukeni ukuze banqobe. Ngokukhula okuqhubekayo kwesikali sokukhiqizwa kwamandla e-hydrogen nengqalasizinda yokugcina nezokuthutha, izindleko zamandla e-hydrogen nazo zinendawo enkulu yokwehla. Ucwaningo lubonisa ukuthi izindleko eziphelele zochungechunge lwezimboni ze-hydrogen kulindeleke ukuthi zehle ngesigamu ngo-2030. Ngokombiko okhishwe ngokuhlanganyela yi-International Hydrogen Energy Commission kanye noMcKinsey, amazwe angaphezu kuka-30 nezifunda zikhiphe umgwaqo wokuthuthukiswa kwamandla e-hydrogen, kanye nokutshalwa kwezimali emhlabeni wonke kumaphrojekthi we-hydrogen energy kuzofinyelela ku-300 billion US dollar ngo-2030
Isitaki samaseli e-hydrogen sakhiwe amaseli amaningi kaphethiloli astakwe ngochungechunge.I-bipolar plate kanye ne-membrane electrode MEA kugqithene ngokushintshana, futhi izimpawu zishumekwe phakathi kwe-monomer ngayinye. Ngemva kokucindezelwa amapuleti angaphambili nangemuva, ayaboshelwa futhi aboshelwe ngezikulufo ukuze enze isitaki se-hydrogen fuel cell.
Ipuleti le-bipolar kanye ne-membrane electrode MEA kugqithene ngokushintshana, futhi izimpawu zishumekwe phakathi kwe-monomer ngayinye. Ngemva kokucindezelwa amapuleti angaphambili nangemuva, ayaboshelwa futhi aboshelwe ngezikulufo ukuze enze isitaki se-hydrogen fuel cell. Okwamanje, isicelo sangempelaipuleti le-bipolar elenziwe nge-graphite yokwenziwa.Ipuleti le-bipolar elenziwe ngalolu hlobo lwezinto eziphathekayo line-conductivity enhle nokumelana nokugqwala. Kodwa-ke, ngenxa yezidingo zokuqina komoya kwepuleti le-bipolar, inqubo yokukhiqiza idinga izinqubo eziningi zokukhiqiza ezifana ne-resin impregnation, i-carbonization, i-graphitization kanye nokucutshungulwa kwenkundla yokugeleza okulandelayo, ngakho inqubo yokukhiqiza iyinkimbinkimbi futhi izindleko ziphezulu kakhulu. ibe yinto ebalulekile evimbela ukusetshenziswa kwe-fuel cell.
I-membrane yokushintshanisa i-protoni-fuel cell (PEMFC) ingaguqula ngokuqondile amandla amakhemikhali abe amandla kagesi ngendlela ye-isothermal kanye ne-electrochemical. Ayinqunyelwe umjikelezo weCarnot, inezinga eliphezulu lokuguqulwa kwamandla (40% ~ 60%), futhi ihlanzekile futhi ayingcolisi (umkhiqizo ikakhulukazi ngamanzi). Kubhekwa njengohlelo lokuqala lokuphakelwa kukagesi olusebenzayo noluhlanzekile ekhulwini lama-21. Njengengxenye yokuxhuma yamaseli angawodwa kusitaki se-PEMFC, ipuleti le-bipolar ngokuyinhloko lidlala indima yokuhlukanisa ukuhlangana kwegesi phakathi kwamaseli, ukusabalalisa uphethiloli kanye ne-oxidant, ukusekela i-electrode ye-membrane nokuxhuma amaseli angawodwa ochungechungeni ukuze enze isifunda se-electronic.
