UFu Yu, obesebenza emkhakheni wezimoto zamaseli kaphethiloli we-hydrogen iminyaka engaphezu kwengu-20, muva nje unomuzwa "wokusebenza kanzima nokuphila okumnandi".

“Ngakolunye uhlangothi, izimoto zamaseli kaphethiloli zizokwenza umbukiso nokukhushulwa kweminyaka emine, kanti intuthuko yezimboni izoletha “isikhathi sefasitela”. Ngakolunye uhlangothi, kuhlaka lomthetho wamandla owakhishwa ngo-Ephreli, amandla e-hydrogen abhalwe ohlelweni lwamandla lwezwe lethu okokuqala, futhi ngaphambi kwalokho, amandla e-hydrogen aphathwa ngokwe “amakhemikhali ayingozi”. Usho ngenjabulo engxoxweni yocingo yamuva nje nentatheli evela e-China News Agency.

Eminyakeni engama-20 edlule, uFu Yu ubelokhu ebandakanyeka ocwaningweni nasekuthuthukisweni eDalian Institute of Chemical Physics, Chinese Academy of Sciences, National Engineering Research Center yemithombo emisha yamandla kagesi kanye nobuchwepheshe bomthombo we-hydrogen, njll. Ufunde noYi Baolian, uchwepheshe wamaseli kaphethiloli kanye nesazi sezemfundo seChinese Academy of engineering. Kamuva, wajoyina ibhizinisi elidumile ukuze asebenze namaqembu eNyakatho Melika, eYurophu, eJapane naseNingizimu Korea, “ukuze azi ukuthi igebe likuphi phakathi kwethu nezinga lesigaba sokuqala emhlabeni, kodwa futhi nokwazi amakhono ethu.” Ekupheleni kuka-2018, waba nomuzwa wokuthi sekuyisikhathi esifanele sokusungula ibhizinisi lesayensi nobuchwepheshe iJi'an hydrogen energy nabalingani abanomqondo ofanayo.

Izimoto ezintsha zamandla zihlukaniswe kakhulu ngezigaba ezimbili: izimoto zebhethri le-lithium kanye nezimoto zamaseli kaphethiloli e-hydrogen. Eyokuqala iye yathandwa ngezinga elithile, kodwa empeleni, izinkinga ezifana nokuhamba ibanga elifushane, isikhathi eside sokushaja, umthwalo omncane webhethri kanye nokuzivumelanisa nezimo zemvelo okungekuhle azikaxazululwa kahle.

UFu Yu nabanye bakholelwa ngokuqinile ukuthi imoto ye-hydrogen fuel cell enokuvikelwa okufanayo kwemvelo ingalungisa ukushiyeka kwemoto yebhethri ye-lithium, okuyisisombululo "esiphezulu" samandla ezimoto.

“Ngokuvamile, kuthatha isikhathi esingaphezu kwesigamu sehora ukuthi imoto kagesi ehlanzekile ishaje, kodwa kuthatha imizuzu emithathu noma emihlanu kuphela emotweni ye-hydrogen fuel cell.” Wanikeza isibonelo. Kodwa-ke, ukuthuthukiswa kwezimboni zezimoto ze-hydrogen fuel cell kusasele kakhulu kunezimoto zebhethri le-lithium, enye yazo ekhawulelwe amabhethri - ikakhulukazi, ngama-stack.

“I-reactor kagesi yindawo lapho kwenzeka khona ukusabela kwe-electrochemical futhi iyisici esiyinhloko sohlelo lwamandla e-fuel cell. Ingqikithi yayo ilingana 'nenjini', okungashiwo futhi ukuthi 'iyinhliziyo' yemoto.” UFu Yu uthe ngenxa yezithiyo zobuchwepheshe eziphakeme, amabhizinisi ambalwa amakhulu ezimoto kanye namaqembu osomabhizinisi ezikhungo zocwaningo lwesayensi ezifanele emhlabeni anekhono lokuklama ubunjiniyela bobuchwepheshe bemikhiqizo ye-reactor kagesi. Uchungechunge lokuhlinzekwa kwemboni yasekhaya yamaseli kaphethiloli e-hydrogen alutholakali kalula, futhi izinga lokufakwa kwendawo liphansi kakhulu, ikakhulukazi ipuleti le-bipolar lezingxenye ezibalulekile, okuwubunzima benqubo kanye "nendawo ebuhlungu" yokusetshenziswa.

Kubikwa ukuthi ubuchwepheshe be-graphite bipolar plate kanye nobuchwepheshe be-metal bipolar plate busetshenziswa kakhulu emhlabeni. Owokuqala unokumelana okukhulu nokugqwala, ukuguquguquka okuhle kanye nokuguquguquka kokushisa, futhi uthatha isabelo esikhulu semakethe esigabeni sokuqala sokuthuthukiswa kwezimboni, kodwa empeleni, futhi unamaphutha athile, njengokuqina komoya okubi, izindleko eziphezulu zezinto kanye nobuchwepheshe bokucubungula obuyinkimbinkimbi. I-metal bipolar plate inezinzuzo zesisindo esilula, ivolumu encane, amandla aphezulu, izindleko eziphansi kanye nenqubo yokusebenza encane, okulindelwe kakhulu ngamabhizinisi ezimoto asekhaya nakwamanye amazwe.

Ngenxa yalesi sizathu, uFu Yu wahola ithimba lakhe ukuba lifunde iminyaka eminingi futhi ekugcineni wakhipha isizukulwane sokuqala semikhiqizo ye-fuel cell metal bipolar plate stack eyathuthukiswa ngokuzimela ekuqaleni kukaMeyi. Lo mkhiqizo usebenzisa ubuchwepheshe be-ultra-high corrosion-resistant and conductive non-noble metal coating technology besizukulwane sesine be-Changzhou Yimai, umlingani oqanjiwe, kanye nobuchwepheshe be-fiber laser welding obunembile kakhulu be-Shenzhen Zhongwei ukuxazulula "inkinga yokuphila" ebilokhu ihlupha imboni iminyaka eminingi. Ngokusho kwedatha yokuhlola, amandla e-reactor eyodwa afinyelela ku-70-120 kW, okuyizinga lesigaba sokuqala emakethe njengamanje; ubukhulu bamandla obuthile bulingana nobe-Toyota, inkampani yezimoto edumile.

Umkhiqizo wokuhlola ubambe i-pneumonia entsha ye-coronavirus ngezikhathi ezibucayi, okwenza uFu Yu wakhathazeka kakhulu. “Bonke abahloli abathathu ababehlelwe ekuqaleni babehlukanisiwe, futhi babekwazi ukuqondisa abanye abasebenzi be-R&D kuphela ukuthi bafunde ukusebenza kwebhentshi lokuhlola ngokusebenzisa i-remote call remote control nsuku zonke. Kwakuyisikhathi esinzima.” Uthe into enhle ukuthi imiphumela yokuhlolwa ingcono kunalokho obekulindelwe, futhi intshiseko yawo wonke umuntu iphezulu kakhulu.

UFu Yu wembule ukuthi bahlela ukwethula inguqulo ethuthukisiwe yomkhiqizo we-reactor kulo nyaka, lapho amandla e-single reactor ezokhushulwa abe ngaphezu kwama-kilowatts angu-130. Ngemva kokufinyelela umgomo "we-reactor yamandla engcono kakhulu eShayina", bazothinta izinga eliphakeme kakhulu emhlabeni, okuhlanganisa ukuphakamisa amandla e-single reactor abe ngaphezu kwama-kilowatts angu-160, ukunciphisa izindleko, ukususa "inhliziyo yaseShayina" enobuchwepheshe obuhle kakhulu, kanye nokukhuthaza izimoto zasekhaya zamaseli e-hydrogen fuel ukuze zishayele "emzileni osheshayo".

Ngokusho kwedatha evela kwi-China Automobile Industry Association, ngo-2019, ukukhiqizwa nokuthengiswa kwezimoto zamaseli kaphethiloli eShayina kwakungu-2833 no-2737 ngokulandelana, okwenyuke ngo-85.5% no-79.2% ngonyaka. Kunezimoto zamaseli kaphethiloli e-hydrogen ezingaphezu kuka-6000 eShayina, futhi umgomo "wezimoto zamaseli kaphethiloli angu-5000 ngo-2020" kumephu yobuchwepheshe yokonga amandla nezimoto ezintsha zamandla usufeziwe.

Njengamanje, izimoto zamaseli kaphethiloli e-hydrogen zisetshenziswa kakhulu emabhasini, emalolini asindayo, ezimotweni ezikhethekile nakwezinye izindawo eShayina. UFu Yu ukholelwa ukuthi ngenxa yezidingo eziphezulu zezokuthutha kanye nezokuthutha mayelana nobude bokukhuthazela kanye nomthamo womthwalo, izinkinga zezimoto zamabhethri e-lithium zizokhuliswa, futhi izimoto zamaseli kaphethiloli e-hydrogen zizobamba le ngxenye yemakethe. Ngokukhula kancane kancane kanye nobukhulu bemikhiqizo yamaseli kaphethiloli, izosetshenziswa kabanzi nasezimotweni zabagibeli esikhathini esizayo.

UFu Yu uphinde waphawula ukuthi uhlaka lwakamuva lokuboniswa nokukhuthazwa kwezimoto zamaseli kaphethiloli zaseShayina luveze ngokusobala ukuthi imboni yezimoto zamaseli kaphethiloli zaseShayina kufanele ithuthukiswe ibe nentuthuko eqhubekayo, enempilo, yesayensi nehlelekile. Lokhu kumenza yena kanye nethimba losomabhizinisi babe nomdlandla futhi bazethembe kakhudlwana.
