Okwangoku, amazwe amaninzi ajikeleze yonke imiba yophando olutsha lwe-hydrogen akwinqanaba elipheleleyo, ubunzima bobugcisa ekunyukeni ukoyisa. Ngokunyuka okuqhubekayo komlinganiselo wemveliso yamandla e-hydrogen kunye nokugcinwa kunye neziseko zokuthutha, iindleko zamandla e-hydrogen nazo zinendawo enkulu yokuncipha. Uphando lubonisa ukuba iindleko ezipheleleyo ze-hydrogen chain industry chain kulindeleke ukuba zehle ngesiqingatha nge-2030. Ngokutsho kwengxelo ekhutshwe ngokudibeneyo yiKomishoni ye-Hydrogen Energy kunye noMcKinsey, amazwe angaphezu kwama-30 kunye nemimandla baye bakhulula i-roadmap yophuhliso lwamandla e-hydrogen, kwaye utyalo-mali lwehlabathi kwiiprojekthi zamandla e-hydrogen ziya kufikelela kwi-300 yeebhiliyoni zeedola zase-US ngo-2030.
Isitaki seeseli zamafutha e-Hydrogen yenziwe ngeeseli ezininzi ze-fuel cell ezipakishwe kuthotho.I-bipolar plate kunye ne-membrane ye-electrode MEA zigqithe ngokutshintshileyo, kwaye izitywina zifakwe phakathi kwe-monomer nganye. Emva kokuba zicinezelwe ngamacwecwe angaphambili nangasemva, zibotshelelwa kwaye zibotshelelwe ngezikrufu ukuze zenze i-hydrogen fuel cell stack.
Ipleyiti ye-bipolar kunye ne-membrane electrode ye-MEA zigqithe ngokutshintshana, kwaye izitywina zifakwe phakathi kwe-monomer nganye. Emva kokucinezelwa ngamacwecwe angaphambili nangasemva, ayabotshelelwa kwaye abotshelelwe ngezikrufu ukwenza isitaki se-hydrogen fuel cell. Okwangoku, esona sicelo sesona sixhoboipleyiti ye-bipolar eyenziwe ngegraphite eyenziweyo.I-bipolar plate eyenziwe ngolu hlobo lwezinto eziphathekayo ine-conductivity enhle kunye nokumelana nokubola. Nangona kunjalo, ngenxa yeemfuno zokuxinana komoya kwipleyiti ye-bipolar, inkqubo yokuvelisa idinga iinkqubo ezininzi zokuvelisa ezifana ne-resin impregnation, i-carbonization, i-graphitization kunye ne-flow flow field processing, ngoko ke inkqubo yokuvelisa inzima kwaye indleko iphezulu kakhulu, ibe yinto ebalulekileyo ethintela ukusetyenziswa kwe-fuel cell.
Proton utshintsho inwebuiseli yamafutha (PEMFC) inokuguqula ngokuthe ngqo amandla ekhemikhali abe ngamandla ombane ngendlela ye-isothermal kunye ne-electrochemical. Ayiphelelanga kumjikelo weCarnot, inezinga eliphezulu lokuguqulwa kwamandla (40% ~ 60%), kwaye icocekile kwaye ayinangcoliseko (imveliso ikakhulu ngamanzi). Ithathwa njengeyona nkqubo yonikezelo lwamandla esebenzayo necocekileyo kwinkulungwane yama-21. Njengenxalenye yokudibanisa iiseli ezilodwa kwi-PEMFC stack, i-bipolar plate idlala indima enkulu yokuhlukanisa i-gas collusion phakathi kweeseli, ukusabalalisa i-fuel kunye ne-oxidant, ukuxhasa i-electrode ye-membrane kunye nokudibanisa iiseli enye kwi-series ukwenza i-electronic circuit.
