Amandla e-hydrogen kunye ne-graphite bipolar plate

Okwangoku, amazwe amaninzi ajikeleze zonke iinkalo zophando olutsha lwe-hydrogen aqhubeka ngokupheleleyo, ubunzima bobuchwephesha ekufuneka buthathwe ukuze buyoyiswe. Njengoko kuqhubeka ukwanda kobungakanani bemveliso yamandla e-hydrogen kunye neziseko zokugcina nezothutho, iindleko zamandla e-hydrogen nazo zinendawo enkulu yokwehla. Uphando lubonisa ukuba iindleko zizonke zekhonkco lamandla e-hydrogen kulindeleke ukuba zehle ngesiqingatha ngo-2030. Ngokwengxelo ekhutshwe ngokudibeneyo yiKhomishini yaMandla e-Hydrogen yamazwe ngamazwe kunye neMcKinsey, amazwe angaphezu kwama-30 kunye nemimandla ikhuphe imephu yendlela yophuhliso lwamandla e-hydrogen, kwaye utyalo-mali lwehlabathi kwiiprojekthi zamandla e-hydrogen luya kufikelela kwi-300 yeebhiliyoni zeedola zaseMelika ngo-2030.

I-Hydrogen fuel cell stack yenziwe zii-fuel cell cell ezininzi ezibekwe ngokulandelelana.Ipleyiti ye-bipolar kunye ne-membrane electrode MEA zidibene ngokwahlukana, kwaye izitywino zifakwa phakathi kwe-monomer nganye. Emva kokucinezelwa ziipleyiti zangaphambili nangasemva, ziyabotshelelwa kwaye zibotshelelwe ngezikrufu ukuze zenze i-hydrogen fuel cell stack.

I-bipolar plate kunye ne-membrane electrode MEA zidibene ngokwahlukana, kwaye izitywino zifakwa phakathi kwe-monomer nganye. Emva kokuba zicinezelwe ziipleyiti zangaphambili nangasemva, zibotshelelwa kwaye zibotshelelwe ngezikrufu ukuze zenze i-hydrogen fuel cell stack. Okwangoku, ukusetyenziswa kwangempela yiipleyiti ye-bipolar eyenziwe ngegrafiti yokwenziwa.Ipleyiti ye-bipolar eyenziwe ngolu hlobo lwento inomoya oqhuba kakuhle kunye nokumelana nokugqwala. Nangona kunjalo, ngenxa yeemfuno zokuqina komoya kwipleyiti ye-bipolar, inkqubo yokuvelisa ifuna iinkqubo ezininzi zemveliso ezifana nokufunxwa kwe-resin, i-carbonization, i-graphitization kunye nokucutshungulwa kwentsimi yokuhamba kwamanzi okulandelayo, ngoko ke inkqubo yokuvelisa iyinkimbinkimbi kwaye iindleko ziphezulu kakhulu, ibe yinto ebalulekileyo ethintela ukusetyenziswa kweseli yamafutha.

I-membrane yokutshintshiselana kweProtonI-fuel cell (PEMFC) inokuguqula ngokuthe ngqo amandla eekhemikhali abe ngamandla ombane ngendlela ye-isothermal kunye ne-electrochemical. Ayinqunyelwanga yiCarnot cycle, inezinga eliphezulu lokuguqulwa kwamandla (40% ~ 60%), kwaye icocekile kwaye ayinangcoliseko (imveliso ikakhulu ngamanzi). Ithathwa njengenkqubo yokuqala yokubonelela ngombane esebenzayo necocekileyo kwinkulungwane yama-21. Njengenxalenye yokudibanisa iiseli ezizimeleyo kwi-PEMFC stack, i-bipolar plate idlala indima yokwahlula i-gas collusion phakathi kweeseli, isasaza i-fuel kunye ne-oxidant, ixhasa i-membrane electrode kwaye idibanisa iiseli ezizimeleyo kuthotho ukwenza i-electronic circuit.
