Parizvino, nyika zhinji dzakapoteredza mativi ese etsvagiridzo yehydrogen itsva iri kutekeshera, matambudziko ehunyanzvi mukukwira kukunda. Nekuenderera mberi kwekuwedzera kwechiyero chekugadzirwa kwesimba rehydrogen uye kuchengetedza uye zvekufambisa zvivakwa, mutengo wesimba rehydrogen zvakare une nzvimbo yakakura yekudzikira. Kutsvakurudza kunoratidza kuti mari yose ye hydrogen energy industry chain inotarisirwa kudonha nehafu kusvika 2030. Maererano nemushumo wakabudiswa pamwe chete neInternational Hydrogen Energy Commission uye McKinsey, nyika dzinopfuura makumi matatu nematunhu dzakabudisa nzira yekuvandudza simba rehydrogen, uye mari yepasi rose mumapurojekiti emagetsi ehydrogen ichasvika 300 mabhiriyoni emadhora eUnited States ne2030.
Hydrogen fuel cell stack inoumbwa neakawanda emafuta masero akaturikidzana munhevedzano.Bipolar plate nemembrane electrode MEA zvakaputirana, uye zvisimbiso zvakaiswa pakati pemonoma imwe neimwe. Mushure mekudzvinyirirwa nemaplateti ekumberi nekumashure, anosungirirwa uye anonamirwa nemascurus kuti aite hydrogen fuel cell stack.
Iyo bipolar ndiro uye membrane electrode MEA inoputirana zvakachinjika, uye zvisimbiso zvakanyudzwa pakati pemonomeri imwe neimwe. Mushure mekudzvinyirirwa nemaplateti ekumberi nekumashure, anosungirirwa uye anosungirirwa nema screws kuti aite hydrogen fuel cell stack.Parizvino, iko kushanda chaikobipolar plate yakagadzirwa negraphite yakagadzirwa.Iyo bipolar plate yakagadzirwa nemhando iyi yezvinhu ine yakanaka conductivity uye kusagadzikana kwemarara. Nekudaro, nekuda kwezvinoda kusimba kwemhepo yebipolar plate, maitiro ekugadzira anoda akawanda maitiro ekugadzira akadai seresin impregnation, carbonization, graphitization uye inotevera kuyerera kwemunda kugadzirisa, saka maitiro ekugadzira akaomarara uye mutengo wakakwira zvakanyanya, Yave chinhu chakakosha chinorambidza kushandiswa kwemafuta sero.
Proton exchange membranefuel cell (PEMFC) inogona kushandura zvakananga kemikari simba kuita simba remagetsi mune isothermal uye electrochemical nzira. Iyo haina kuganhurirwa neCarnot cycle, ine yakakwira simba rekushandura chiyero (40% ~ 60%), uye yakachena uye isina kusvibiswa-isina (chigadzirwa chinonyanya mvura). Inofungidzirwa kuti ndiyo yekutanga inoshanda uye yakachena magetsi system muzana ramakore re21. Sechikamu chekubatanidza chemasero mamwechete muPEMFC stack, bipolar plate inonyanya kuita basa rekuparadzanisa gasi kuwirirana pakati pemasero, kugovera mafuta uye oxidant, inotsigira membrane electrode uye kubatanidza masero mamwechete mumutsara kuti aumbe magetsi emagetsi.
