Parizvino, nyika dzakawanda dziri muzvikamu zvese zvekutsvagisa kwehydrogen dziri kufamba zvakanyanya, matambudziko ehunyanzvi ari kutorwa kuti agadziriswe. Nekuwedzera kuri kuramba kuchiita huwandu hwekugadzirwa kwesimba rehydrogen, kuchengetedza nekufambisa, mutengo wesimba rehydrogen une mukana mukuru wekuderera. Tsvagiridzo inoratidza kuti mutengo wese weindasitiri yesimba rehydrogen unotarisirwa kudzikira nehafu panosvika gore ra2030. Sekureva kwemushumo wakaburitswa pamwe chete neInternational Hydrogen Energy Commission neMcKinsey, nyika dzinopfuura makumi matatu nenzvimbo dzakaburitsa gwara rekuvandudza simba rehydrogen, uye mari yepasi rose mumapurojekiti esimba rehydrogen ichasvika mabhiriyoni mazana matatu emadhora ekuAmerica panosvika gore ra2030.
Hydrogen fuel cell stack inoumbwa nemasero akawanda efuel cell akarongwa akatevedzana.Bipolar plate ne membrane electrode MEA zvinopindirana zvichichinjana, uye zvisimbiso zvinoiswa pakati pe monomer yega yega. Mushure mekudzvanywa nemaplate epamberi neekumashure, zvinosungirirwa uye zvinosungirirwa nezvikuruu kuti zvigadzire stack yehydrogen fuel cell.
Iyo bipolar plate ne membrane electrode MEA zvakabatana zvakatevedzana, uye zvisimbiso zvinoiswa pakati pe monomer yega yega. Mushure mekudzvanywa nemaplate epamberi neekumashure, zvinosungirirwa uye zvinosungirirwa nezvikururu kuti zvigadzire stack yehydrogen fuel cell. Parizvino, kushandiswa chaiko ndikondiro yebipolar yakagadzirwa negirafiti yekugadzira.Purati yebipolar yakagadzirwa nezvinhu izvi ine conductivity yakanaka uye inodzivirira ngura. Zvisinei, nekuda kwezvinodiwa kuti plate yebipolar igare yakasimba, maitiro ekugadzira anoda maitiro akawanda ekugadzira akadai sekuiswa kwe resin, carbonization, graphitization uye flow field processing inotevera, saka maitiro ekugadzira akaomarara uye mutengo wakakwira zvikuru, Yave chinhu chakakosha chinodzivisa kushandiswa kwe fuel cell.
Kamudzira kekuchinjana kwemapurotoniSero remafuta (PEMFC) rinogona kushandura simba remakemikari zvakananga kuita simba remagetsi nenzira ye isothermal uye electrochemical. Harigumiriswi neCarnot cycle, rine simba rakawanda rekushandura (40% ~ 60%), uye rakachena uye harina kusvibiswa (chigadzirwa chacho chinonyanya kuva mvura). Rinoonekwa senzira yekutanga yemagetsi inoshanda uye yakachena muzana remakore rechi21. Sechikamu chinobatanidza masero ega ega muPEMFC stack, bipolar plate inonyanya kuita basa rekuparadzanisa gasi pakati pemasero, kugovera mafuta ne oxidant, kutsigira membrane electrode uye kubatanidza masero ega ega mumutsara kuti agadzire electronic circuit.
