Nā pūnaewele no ka waika formic

Hiki ke hiki i ka 100% ka mana o ka hoʻololi ʻana i ka ikehu kemika i ka ikehu uila i nā wahie. ʻO ka pākēneka, akā i kēia manawa ka mea maikaʻi loa o lākou he hydrogen - loaʻa iā lākou ka pono a hiki i ka 60%. He liʻiliʻi lākou, ʻoi aku ka māmā ma mua o nā mea ma mua a, ʻaʻole like me nā pākahi maʻamau, hāʻawi i ka hana mau. He mea pono e hoʻomanaʻo i ka pono o ka haʻahaʻa haʻahaʻa i loko o nā ʻenekini hoʻopau wale nō ma kahi o 100% -? wahi a Kauka Hub. Pelekania Andrzej Borodzinski mai IPC PAS.

ʻO ke kelepona wahie he mea hoʻololi i ka ikehu kemika i uila. Hoʻokumu pololei ʻia ke ʻano ma muli o ka puhi ʻana i ka wahie i mua o nā catalysts i hoʻohana ʻia ma ka anode a me ka cathode o ke kelepona. ʻO ke keakea nui loa i ka hoʻolaha ʻia ʻana o nā cell hydrogen ʻo ka mālama ʻana i ka hydrogen. Ua hōʻike ʻia kēia pilikia he paʻakikī loa mai ka ʻike loea a ʻaʻole naʻe i hoʻopau ʻia me nā hopena ʻoluʻolu. ʻO ka hoʻokūkū me nā pūnaewele hydrogen he mau pūnaeau methanol. Eia nō naʻe, he mea ʻawaʻawa ka methanol ponoʻī, a pono e kūkulu ʻia nā mea e ʻai ai me ka hoʻohana ʻana i nā catalysts platinum pipiʻi. Eia hou, he haʻahaʻa ka mana o nā methanol a hana ma kahi kiʻekiʻe, a no laila hiki ke pilikia ka wela (ma kahi o 90 degere).

ʻO kahi hopena ʻē aʻe ʻo ia ka formic acid fuel cell. Hoʻomaka ka hopena ma ka lumi wela, a ʻoi aku ka kiʻekiʻe o ka pono a me ka mana o ke kelepona ma mua o ka methanol. Eia kekahi, ʻo ka formic acid kahi mea maʻalahi e mālama a lawe aku. Eia nō naʻe, pono ka hana paʻa o ka cell acid formic i kahi catalyst kūpono a paʻa. ʻO ka catalyst a mākou i kūkulu mua ai he haʻahaʻa haʻahaʻa ma mua o nā catalysts palladium maʻemaʻe i hoʻohana ʻia i kēia manawa. Eia naʻe, nalowale ka ʻokoʻa ma hope o ʻelua hola o ka hana. ʻoi aku ka maikaʻi. ʻOiai ke hoʻomau nei ka emi ʻana o ka hana o ka catalyst palladium maʻemaʻe, paʻa kā mākou, "wahi a Dr. Borodzinsky.

ʻO ka maikaʻi o ka catalyst i hoʻomohala ʻia ma IPC surfactant, ʻo ia ka mea koʻikoʻi mai kahi ʻike waiwai, ʻo ia ka mālama ʻana i kāna mau waiwai i ka wā e hana ai i ka waika formic haʻahaʻa. Hiki ke hana maʻalahi kēia ʻano ʻakika formic i nā mea nui, me ka biomass, no laila hiki ke maʻalahi ka wahie no nā cell hou. He wahie ʻōmaʻomaʻo loa i loaʻa mai i ka biomass formic acid. ʻO nā huahana o nā hopena i hana ʻia me kona komo ʻana i loko o nā wahie he wai a me carbon dioxide. ʻO ka hope he kinoea ʻōmaʻomaʻo, akā loaʻa ka biomass mai nā mea kanu e hoʻomoʻa iā ia i ko lākou ulu ʻana. ʻO ka hopena, ʻaʻole e hoʻololi ka hana o ka formic acid mai ka biomass a me kāna ʻai ʻana i nā cell i ka nui o ka carbon dioxide i ka lewa. He haʻahaʻa hoʻi ka pilikia o ka hoʻohaumia ʻana i ke kaiapuni e ka formic acid.

E loaʻa i nā pūnaeau wahie formic acid i nā noi he nui. E ʻoi aku ka kiʻekiʻe o kā lākou pono i nā mea uila uila? kelepona paʻa lima, laptops, GPS. Hiki ke hoʻokomo ʻia kēia mau mea e like me nā kumu mana no nā kaʻa mai nā noho huila a hiki i nā kaʻa uila a me nā yachts.

Ma IPC PAS, ke hoʻomaka nei ka noiʻi ʻana i nā pākaukau mua i kūkulu ʻia mai nā pūnaeau wahie formic acid. Manaʻo nā kānaka ʻepekema e mākaukau kahi prototype o kahi mea pāʻoihana i loko o kekahi mau makahiki.
