Ko te pereti rua-pōro te wāhanga matua o te tauhohenga, he nui te pānga ki te mahi me te utu o te tauhohenga. I tēnei wā, ko te pereti rua-pōro e wehea ana ki te pereti karāti, te pereti hiato me te pereti whakarewa e ai ki te rauemi.
Ko te pereti bipolar tētahi o ngā wāhanga matua o te PEMFC, ko tana mahi matua he kawe i te hau mā roto i te papa rere o te mata, te kohikohi me te whakahaere i te iahiko, te wera me te wai i puta mai i te tauhohenga. I runga i te momo rauemi, ko te taumaha o te puranga PEMFC he tata ki te 60% ki te 80%, ā, ko te utu he tata ki te 30%. E ai ki ngā whakaritenga mahi o te pereti bipolar, me te whakaaro ki te taiao tauhohenga hikohiko waikawa o te PEMFC, me whai te pereti bipolar i ngā whakaritenga teitei mō te kawe hiko, te ātete hau, ngā āhuatanga miihini, te ātete waikura, me ētahi atu.
E ai ki ngā rauemi, ka wehea te pereti takirua ki ngā wāhanga e toru: te pereti karāhe, te pereti hiato, te pereti whakarewa, me te pereti takirua karāhe, koinei te pereti takirua PEMFC o te whare e whakamahia whānuitia ana i ēnei rā. He pai te kawe hiko, te kawe wera, te pumau me te ātete ki te waikura, engari he iti noa ngā āhuatanga miihini, he pakarukaru, ā, he nui te utu o ngā raruraru miihini. He maha ngā kaihanga e raru ana i te utu nui.
Karāpitipereti rua-irakupu whakataki
He pai te kawe hiko, te kawe wera me te ātete ki te waikura o ngā pereti rua-pōro i hangaia ki te karāpeti, ā, koinei ngā pereti rua-pōro e whakamahia whānuitia ana i roto i ngā PEMFCS. Heoi, he mārama ake hoki ōna ngoikoretanga: ko te pāmahana whakakārāpeti o te pereti karāpeti he teitei ake i te 2500℃, me mahi i runga i te tikanga whakamahana tino kaha, ā, he roa te wā; he puhoi te tukanga miihini, he roa te huringa, ā, he nui te tika o te mīhini, ka hua ake he utu nui mō te pereti karāpeti; he pakarukaru te karāpeti, me āta whakahaere te pereti kua oti, he uaua te huihui; he pūwero te karāpeti, nō reira me torutoru mirimita te matotoru o ngā pereti kia taea ai te wehe i ngā hau, ka hua ake he iti ake te mātotoru o te rauemi tonu, engari he taumaha ake te hua kua oti.
Te whakarite i te karāpetipereti rua-ira：
Ka konatunatua te paura toner, te paura karāpeti rānei ki te kapia kua whakakārāpetihia, ka hangaia he mea pēhi, ka whakakārāpetihia ki te pāmahana teitei (i te nuinga o te wā i te 2200~2800C) i roto i te hau whakaiti, i raro rānei i ngā āhuatanga korehau. Kātahi ka whakakīia te pereti karāpeti hei hiri i te kōhao, kātahi ka whakamahia te mīhini whakahaere tau hei tukatuka i te ara hau e hiahiatia ana i runga i tōna mata. KO TE WHAKAKĀRITI PĀMAHANA TITE ME TE MĪHINIHANGA O NGĀ HONGERE HAUREHU NGĀ TAKE MATUA MŌ TE UTU NUI O NGĀ PEREITI PŪRARU, ME TE WHAKATAU MĪHINIHANGA MŌ TE 60% O TE UTU PŪTAU WAIRUA KATOA.
Pereti rua-irako tētahi o ngā wāhanga matua o te puranga pūtau wahie. Ko ōna mahi matua koia ēnei:
1, Hononga pākahiko kotahi
2、Tukuna te wahie (H2) me te hau (02)
3、Te kohikohinga me te kawe iahiko
4, Puranga tautoko me te MEA
5. Hei tango i te wera i puta mai i te tauhohenga
6, Ringihia te wai i puta mai i te tauhohenga
