I-Yokey inikeza izixazululo zokuvala zonke izinhlelo zokusebenza ze-PEMFC kanye ne-DMFC fuel cell: zesitimela sokushayela imoto noma iyunithi yamandla asekelayo, ukufakwa kokushisa namandla okuzenzakalelayo noma okuhlanganisiwe, izitaki ezixhunywe ngaphandle kwegridi/gridi, kanye nokuzilibazisa. Njengenkampani ehamba phambili yomhlaba wonke yokuvala, sinikeza izixazululo eziphelele kwezobuchwepheshe nezingabizi kakhulu zezinkinga zakho zokuvala.
Umnikelo wethu okhethekile wokuvala izikhala embonini yamaseli kaphethiloli ukuhlinzeka ngomklamo ongcono kakhulu ngezinto zethu ezifanelekayo zamaseli kaphethiloli esizikhiqizayo kunoma yisiphi isigaba sokuthuthukiswa kusukela kumthamo omncane weprototype kuya ekukhiqizweni komthamo omkhulu. I-Yokey ihlangabezana nalezi zinselele ngezixazululo ezahlukahlukene zokuvala izikhala. Iphothifoliyo yethu ephelele yokuvala ihlanganisa ama-gasket akhululekile (asekelwayo noma angasekelwayo) kanye nemiklamo ehlanganisiwe kumapuleti e-bipolar ensimbi noma e-graphite kanye nezinto ezithambile ezifana nezinto zohlaka lwe-GDL, i-MEA kanye ne-MEA.
Imisebenzi eyinhloko yokuvala ukuvimbela ukuvuza kwamagesi okupholisa kanye nama-reactant kanye nokubuyisela ukubekezelelana kokukhiqiza ngamandla amancane omugqa. Ezinye izici ezibalulekile zomkhiqizo zifaka phakathi ukuphathwa okulula, ukuqina kokuhlanganiswa, kanye nokuqina.
