I roto i ngā pūnaha pūngao hikohiko e whanake tonu ana,te muka whatuHe rauemi waro-maha tēnei e tū ana, he āhuatanga hanganga, hiko, me te matū ahurei. Ahakoa kāore i te whakamahia katoatia e ngā hoahoa pūtau wahie te muka karāhe, ko tōna tūranga—ina koa i roto i ngā pūnaha pūtau wahie matatau me ngā pūnaha pūtau wahie ranu—kua piki haere te aro o ngā kaihangarau me ngā kaihoahoa pūnaha e aro nui ana ki te arotau i te mahi pūtau wahie i ngā taumata rauemi me te tukanga.
I. Ngā āhuatanga taketake o te huruhuru graphite
Mai i te tirohanga pūtaiao rauemi, he whatunga pūwero toru-ahu te whatu karāpeti i hangaia mai i ngā muka waro kua rarangahia, i ahu mai i te polyacrylonitrile (PAN) i ngā matū mua rānei o te pitch, ā, kua whakakārāpetihia ki ngā pāmahana teitei. Nā tēnei hanganga ka whakawhiwhia te whatu karāpeti ki ngā āhuatanga maha, he mea nui i roto i ngā taiao hikohiko:
● Te kawe hiko teitei: te whakarite i te kawe irahiko
● Teitei o te pūwero (>90%): e āwhina ana i te urunga o te hau, te wai rānei
● He ātete kaha ki te waikura: ka taea te urutau ki ngā taiao waikawa/waikura (hei tauira, ngā PEMFC)
● He pai te ātete ki te pēhanga: e whai wāhi ana ki te pumau o te pa
● Ātete pāmahana teitei: he pai mō ngā pūnaha hikohiko pāmahana teitei
II. Te Tūranga o te Karāpiti i roto i ngā Pūtau Wahie Rerekē
He rerekē te whakamahinga o te whatu karāpeti i roto i te hangarau pūtau wahie i runga i te hoahoa o te pūnaha.
1. Ngā Pūhiko Rere-ā-roto (hei tauira, ngā pūhiko rere-ā-whero vanadium) – Rauemi Hiko Matua
I roto i ngā pūnaha hikohiko ā-wai – inā koa ko ngā pākahiko rere, e kōrerohia ana i te taha o te hangarau pūtau wahie nā te mea he rite tonu ngā mātāpono hikohiko – ka whakamahia te huruhuru karāpeti hei rauemi hiko matua. Ko tōna horahanga mata motuhake teitei me tōna hanganga pūwero honohono e whakarato ana i ngā pae hohe maha mō ngā tauhohenga redox me te whakatairanga i te rere o te irahiko. Ko ngā tukanga whakarerekētanga mata pēnei i te whakahohenga wera, te waikura rānei, ka whakamahia hei whakarei ake i tōna kaha whakamakuku me te mahi whakatere, ka pā tika ki te pai o te pūnaha me te pumau o te huringa.
2. I roto i ngā Pūtau Wahie PEM (Ngā Pūtau Wahie Kiriuhi Whakawhiti Proton) – Rauemi Tautoko/Tohatoha Āwhina
He rerekē, i roto i ngā pūnaha membrane whakawhiti proton (PEM), ehara te whatu karāpiti i te kōwhiringa noa mō te paparanga horapa hau (GDL). Ko te pepa waro, ko te kakahu waro rānei te mea nui nā tōna taurite pai o te kawe hiko, te pakari ā-mīhini, me te āheinga hanga. Heoi, kua kitea he whakamahinga ahurei o te whatu karāpiti i roto i ētahi whirihoranga PEM motuhake, inā koa ka hiahiatia te whakahaere wai whakarei ake, te tohatoha hau rānei. Ka taea e tōna porosity teitei te whakapai ake i te mahi whakawhiti papatipu i raro i te haumākū teitei, i ngā āhuatanga makuku rānei, engari ka puta he taupatupatu i roto i te ātete pa me te pumau pēhanga, me aro atu mā te whakahaere puranga me te pēhanga kua hoahoatia kia tupato.
3. I roto i ngā Pūtau Wahie Pāmahana-Teitei (SOFC, me ētahi atu) – Āwhina Ārahi/Hīnga Āwhina
I roto i ngā pūnaha pāmahana teitei (hei tauira, ngā irahiko waikura totoka), kāore te huruhuru karāpiti e whakamahia hei wāhanga hiko matū matua nā te mea he nui ngā rauemi uku i roto i ngā irahiko me te irahiko. Heoi, ka taea e ia te mahi i ngā mahi āwhina, tae atu ki te ārai i te kawe hiko, te tautoko hiri, te whakauru rānei i te whakawhānui wera i roto i ngā taputapu āwhina, i ngā rohe ā-kanohi rānei. Ahakoa he tuarua ēnei mahi, he mea nui kia mau tonu te roa me te pono o te miihini i raro i ngā āhuatanga mahi tino kino.
III. Whakarāpopototanga o ngā Tūranga Matua i roto i te Hangarau Pūtau Wahie
Mai i te tirohanga hangarau tukanga, ko te uara o te whatu karāpeti kei roto i tōna kaha ki te whakauru i ngā mahi maha ki roto i te rauemi kotahi. Mā tōna hanganga toru-ahu ka taea te hanga i ngā atanga hikohiko whānui, ka whakanui ake i te horahanga tauhohenga hohe me te kore e whakanui nui i te tapuwae pūnaha. I te wā kotahi, ka whai wāhi ki te tohatoha wai ōrite, ka whakaiti i ngā pikinga kukū me te whakaiti i ngā ngaronga porowhita e pā ana ki ngā herenga whakawhiti papatipu. Mā te whakaurunga tika o te whatu karāpeti ka āwhina i te hanganga o tētahi whatunga kawe hiko tonu, ka whakaiti i te ātete ā-roto me te whakapai ake i te whai huatanga whānui o te pūnaha.
Hei tāpiritanga, he mahi nui tāna ki te arotau i ngā mahi miihini me ngā mahi huihuinga. Mā te kaha ki te pēhi me te pakari o te huruhuru karāhe ka taea te urutau ki ngā ātete hanga me te pupuri i te hononga ā-mata pumau i raro i ngā āhuatanga whakarārangi. He tino painga tēnei āhuatanga i roto i ngā pūnaha modular, i ngā pūnaha tauine nui rānei, nā te mea he mea nui te tohatoha ōrite mō te ōritetanga o te mahi.
