I-Yokey inikeza izixazululo zokuvala kuzo zonke izinhlelo zokusebenza ze-PEMFC ne-DMFC zamaseli kaphethiloli: ngesitimela esishayela izimoto noma iyunithi yamandla asizayo, ukushisa okumile noma okuhlanganisiwe nokufakwa kwamandla, izitaki ze-off-grid/grid exhunyiwe, nokuzilibazisa. Njengoba siyinkampani ehamba phambili yokuvala uphawu emhlabeni wonke sinikeza izixazululo eziphelele ngobuchwepheshe nezithengekayo zezinkinga zakho zokuvala.
Isici sethu esikhethekile embonini yamangqamuzana kaphethiloli ukuhlinzeka ngedizayini engcono kakhulu ngezinto zethu ezifanelekayo ze-fuel cell esizenzela noma yisiphi isigaba sokuthuthuka ukusuka kumthamo omncane we-prototype kuya ekukhiqizweni kwevolumu ephezulu. I-Yokey ihlangabezana nalezi zinselele ngezixazululo ezihlukahlukene zokuvala. Iphothifoliyo yethu ebanzi yokuvala ifaka ama-gaskets axegayo (asekelwayo noma angasekelwe) kanye nemiklamo ehlanganisiwe kumapuleti ensimbi noma e-graphite bipolar kanye nezinto ezithambile ezifana ne-GDL, i-MEA kanye nempahla yozimele ye-MEA.
Imisebenzi eyinhloko yokuvala iwukuvimbela ukuvuza kwamagesi apholileyo kanye ne-reactant kanye nokunxephezela ukubekezelela ukukhiqizwa ngamandla amancane emigqa. Ezinye izici zomkhiqizo ezibalulekile zihlanganisa ukuphatha kalula, ukuqina komhlangano, nokuqina.
