Waikawa Formic Ngā Pūtau Wahie
Ka whakamahia hoki te waikawa formic hei wahie i roto i ngā pūtau wahie waikawa formic tika (DFAFC). I roto i ēnei pūtau wahie, ka mahi te waikawa formic hei wahie, ka pāngia e te tauhohenga waikura i te anode hei tuku i ngā irahiko me te whakaputa pūngao hiko. He painga ngā DFAFC pēnei i te kiato pūngao teitei me te pāmahana whakahaere iti, ā, he pai ngā tono pea i roto i ngā taputapu hiko iti me ngā pūtake hiko kawe.

Ngā Painga o ngā Pūtau Wahie Waikawa Formic (DFAFC)
Ko ngā pūtau wahie waikawa formic tika (DFAFC) he hangarau whakawhiti pūngao hikohiko tino whaihua, e tuku ana i tētahi huinga ahurei o te haumaru teitei, te whai huatanga tino pai, me te whakahaeretanga whai hua e aro ana ki ngā herenga nui o ngā huarahi kē atu i runga i te hauwai me te methanol.
Hei wahie wai i te pāmahana rūma me te pēhanga hau, ka whakakorea e te waikawa formic (HCOOH) te hiahia mō te pēhanga teitei, te rokiroki cryogenic rānei, ka tino whakaiti i ngā utu hanganga me ngā mōrearea haumaru e pā ana ki te whakahaere hauwai. Ki te whakatauritea ki ngā pūtau wahie methanol tika (DMFC), he iti rawa te tere whakawhiti wahie o ngā DFAFC mā roto i ngā kiriuhi whakawhiti proton (PEM). Nā te pana hiko i waenga i te anion formate (HCOO⁻) me ngā rōpū waikawa sulfonic i roto i te kiriuhi tēnei, e āhei ai te whakamahi i te wahie kukū teitei (tae atu ki te 20 mol/L) hei whakanui ake i te kiato pūngao rōrahi (4.4 kWh/dm³) me te kore he ngaronga whai hua.
I runga i te hikohiko, he nui ake te ngaohiko ara iahiko tuwhera o ngā DFAFC (1.48 V) i ngā PEMFC hauwai (1.23 V) me ngā DMFC (1.20 V), ā, he nui ake te putanga mana pūmanawa. Kāore he hononga CC i roto i te ngota waro-kotahi, e āhei ai te tere o te nekeneke waikura me te iti o te hanganga o ngā takawaenga CO e paitini ana i ngā whakakorikori konukawata. Ka hua ake tēnei i te mahi pumau ake, ā, he maha ngā wā ka taea te whakamahi i ngā whakakorikori palladium he iti ake te utu.
Hei tāpiritanga, he iti te paitini o te waikawa formic (kua whakaaetia e te FDA hei tāpiringa kai) ā, he iti ake te mura i te methanol, e whakangawari ana i te kawe, te rokiroki, me ngā tikanga haumaru mō ngā kaiwhakamahi mutunga. He mea nui, ka taea te hanga waikawa formic i runga i te pumau mā te whakaiti hiko CO₂, ka hangaia he porowhita waro kati, ā, ka waiho ngā DFAFC hei hangarau matua mō te whakatutuki i te kore waro i roto i ngā hiko kawe, ngā putunga hiko iti, me ngā tono mamao i waho o te whatunga.
