ʻO ka loina o ka membrane exchange Proton, ka mākeke a me kā mākou hana proton o ka hoʻokomo ʻana i ka huahana membrane exchange

In memo hoʻololi protonwahie cell, ka catalytic oxidation o nā protons he cathode i loko o ka membrane, i ka manawa like, ka anode o nā electrons e neʻe i ka cathode ma o kahi kaapuni o waho, ka qualitative i hui pū ʻia me ka uila a me ka cathodic hōʻemi o ka oxygen ma ka ʻili o ka wai i hana ʻia, ka ikehu i hana ʻia e ka uila ma o ka hoʻokele kaapuni waho. I ka typical proton exchange membrane fuel cell membrane electrode a ʻo ka pono ke kumu nui, a ʻo ka conductivity proton kiʻekiʻe he mea koʻikoʻi o nā mea membrane exchange proton. ʻO ka membrane hoʻololi Proton ka mea maʻamau i ka hoʻokaʻawale maikaʻi ʻana o ka hydrophobic a me ka hydrophilic, ka hale hydrophobic e pale aku ai i ka nui o ka wai absorption, e hoʻohaʻahaʻa i ka pehu o ka membrane, e mālama i ka paʻa mechanical o ka membrane; ʻO nā pūʻulu hydrophilic o ka sulfate ke alakaʻi nei i ke kahawai i lawa, hiki ke protons mai ka anode a i ka cathode, ka hui ʻana o ke kinoea i ka manawa like.

Loaʻa nā hemahema o ke kumukūʻai kiʻekiʻe a me ke ola pōkole ma muli o ka hoʻohana ʻana i nā sulfonated polystyrene-styrene copolymer membranes. I nā makahiki 1970, ua hoʻololi ka membrane Nafion i ka sulfonated polystyrogen-divinylbenzene copolymer membrane e like me ka membrane maʻamau no nā pūnaehu wahie membrane hoʻololi proton.

Pono e hana ka membrane sulfonic acid a pau ma lalo o 100 ° C, a i ka wā i ʻoi aku ka kiʻekiʻe o ka mahana ma mua o 100 ° C, e hoʻomaloʻo koke ka membrane a hāʻule nā ​​​​ʻāpana ionic i loko o ka hale membrane, e hopena i ka emi nui o ka conductivity. . I kēia manawa, hana ka hapa nui o nā wahie i nā mahana ma lalo o 100 ° C, akā ʻaʻole maikaʻi kēia. No laila,nā membrane hoʻololi protonhiki ke hoʻololi i nā wela kiʻekiʻe e pono e hoʻomohala hou. He hopena koʻikoʻi ka pae hana i ke kumukūʻai hana o ka membrane exchange proton. ʻO ke kumu kūʻai o ka membrane hoʻololi proton ka nui o nā ʻāpana ʻekolu: (1) ke kumu kūʻai o ka ionomer; (2) Kumu kūʻai waiwai o ka polytetroxene i hoʻonui ʻia a me (3) kumukūʻai hana kiʻiʻoniʻoni. Hoʻopili ʻia ke kumukūʻai waiwai a me ka hana ʻana i ka lāʻau e ka paona hana. Ke piʻi aʻe ka pālākiō hana mai 1000 sets / makahiki i 10000 sets / makahiki, hiki ke hoʻemi ʻia ke kumukūʻai hana o ka hoʻololi proton a me ka hoʻololi kiʻiʻoniʻoni e 77% a hiki ke hoʻemi ʻia ka huina kālā e 70%.

ʻO VET Technology Co., Ltd ka keʻena ikehu o VET Group, he ʻoihana ʻenehana kiʻekiʻe o ka ʻāina i ka noiʻi a me ka hoʻomohala ʻana, ka hana ʻana, ke kūʻai aku a me ka lawelawe ʻana i nā ʻāpana kaʻa a me nā ʻāpana ikehu hou, ʻo ia ka mea e pili ana i ka moʻo kaʻa, nā ʻōpala ʻōpala. wahie cell & flow battery, a me na mea hou hou.

I loko o nā makahiki, ua hōʻiliʻili mākou i kahi pūʻulu o nā talena ʻoihana loea a me nā hui R&D, a loaʻa iā mākou ka ʻike kūpono i ka hoʻolālā huahana a me nā noi ʻenehana. Ua hoʻokō mau mākou i nā holomua hou i ka hana ʻana i nā lako hana ʻenehana a me ka hoʻolālā laina semi-automated, e hiki ai i kā mākou hui ke hoʻomau i ka hoʻokūkū ikaika ma ka ʻoihana like.

Me nā mana R & D mai nā mea koʻikoʻi a hiki i ka hoʻopau ʻana i nā huahana noi, ua loaʻa i ke kumu a me nā ʻenehana koʻikoʻi o nā kuleana waiwai naʻauao kūʻokoʻa i ka nui o nā hana ʻepekema a me nā ʻenehana. Ma muli o ka maikaʻi o ka huahana paʻa, ke kumu hoʻolālā hoʻolālā maikaʻi loa a me ka lawelawe ma hope o ke kūʻai aku, ua lanakila mākou i ka ʻike a me ka hilinaʻi mai kā mākou mea kūʻai aku.

ʻO nā membrane Nafion PFSA i hana ʻia e VET Energy he mau membrane i hoʻoikaika ʻole ʻia e pili ana i nā polymers Nafion PFSA, perfluorinated sulfonic acid/polytetrafluoroethylene copolymers ma ka ʻakika (H+). Hoʻohana nui ʻia nā membranes Nafion PFSA mamemo hoʻololi proton(PEM) wahie a me ka wai electrolysers. I loko o nā ʻano mea like ʻole electrochemical, hana nā membrane ma ke ʻano he mea hoʻokaʻawale a me nā electrolytes paʻa a koi ʻia e koho i nā cations ma o nā hui pūlima. ʻO ka polymer he mea pale kemika a lōʻihi.
