Ka taea te wehewehe i ngā pūtau wahie kikiriuhi whakawhiti pūmuangā pūtau wahie (PEMFC) me ngā pūtau wahie methanol tika e ai ki ngā āhuatanga electrolyte me te wahie e whakamahia ana
(DMFC), pūtau wahie waikawa phosphoric (PAFC), pūtau wahie warowaihā rewa (MCFC), pūtau wahie waikura totoka (SOFC), pūtau wahie kawakore (AFC), me ētahi atu. Hei tauira, ko ngā pūtau wahie kiriuhi whakawhiti proton (PEMFC) e whakawhirinaki ana kikiriuhi whakawhiti pūmuaI roto i te reo whakawhiti porotana, ka whakamahia e ngā pūtau wahie kawakore (AFC) te irahiko wai-wai kawakore pērā i te otinga pāhare pākawa hei reo whakawhiti porotana. Hei tāpiri, e ai ki te pāmahana mahi, ka taea te wehewehe i ngā pūtau wahie ki ngā pūtau wahie pāmahana teitei me ngā pūtau wahie pāmahana iti. Ko te tuatahi ko ngā pūtau wahie waikura totoka (SOFC) me ngā pūtau wahie warowaihā rewa (MCFC). Ko te tuarua ko ngā pūtau wahie kiriuhi whakawhiti porotana (PEMFC), ngā pūtau wahie methanol tika (DMFC), ngā pūtau wahie kawakore (AFC), ngā pūtau wahie waikawa phosphoric (PAFC).
Kiriuhi whakawhiti pūmuaKa whakamahia e ngā pūtau wahie (PEMFC) ngā kiriuhi pūmua waikawa wai-pūmua hei irahiko. Me mahi ngā pūtau PEMFC i raro i te hau hauwai parakore nā te mea he iti te pāmahana whakahaere (i raro i te 100°C) me te whakamahinga o ngā irahiko whakarewa rangatira (ngā irahiko kei runga i te konupūmā). Ki te whakatauritea ki ētahi atu pūtau wahie, he iti te pāmahana whakahaere, he tere tīmatanga tere, he nui te kaha, he irahiko kore-waikura, ā, he roa te ora mahi. Nō reira, kua noho koia te hangarau matua e whakamahia ana i tēnei wā ki ngā waka pūtau wahie, engari he wāhanga anō hoki e whakamahia ana ki ngā taputapu kawe me ngā taputapu tūmau. E ai ki a E4 Tech, e matapaetia ana ka eke ngā tuku pūtau wahie PEMFC ki te 44,100 waeine i te tau 2019, e 62% o te wahanga o te ao; Ko te kaha tāuta e matapaetia ana ka eke ki te 934.2MW, e 83% o te wahanga o te ao.
Ka whakamahia e ngā pūtau wahie ngā tauhohenga hikohiko hei huri i te pūngao matū mai i te wahie (hauwai) i te anode me te waikura (hāora) i te cathode hei hiko hei taraiwa i te waka katoa. Ina koa, ko ngā wāhanga matua o ngā pūtau wahie ko te pūnaha miihini, te puna hiko āwhina me te motuka; i roto i ēnei, ko te pūnaha miihini te nuinga o te wā ko te miihini e titoa ana e te tauhohenga hiko, te pūnaha rokiroki hauwai waka, te pūnaha whakamatao me te kaitahuri hiko DCDC. Ko te tauhohenga te wāhanga tino nui. Koinei te wāhi e tauhohe ai te hauwai me te hāora. He maha ngā pūtau takitahi e whakatakotoria ana, ā, ko ngā rauemi matua ko te pereti bipolar, te hiko membrane, te pereti pito me ētahi atu.
