1. ʻO ka hoʻohana nui ʻana i ka waika formic a me ka holomua noiʻi i loko o nā wahie
Ma ke ʻano he mea mālama hydrogen, hiki i ka waikawa formic ke hoʻokuʻu i ka nui o ka hydrogen no ka hoʻohana ʻana e ka hopena kūpono inā pono, a he kikowaena paʻa ia no ka hoʻohana ākea a me ka halihali palekana o ka ikehu hydrogen.
ʻAʻole hiki ke hoʻohana nui ʻia ka waika Formic wale nō i nā mea ʻenehana a me nā mea kemika, akā hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻoheheʻe hau hoʻoheheʻe kaiapuni hou e pale ai i ka pollution wai.
Hiki ke hoʻohana ʻia ka waiuma formic no ka hana ʻana i nā pūnaeau wahie e hoʻohana pono ana i ka waiuma formic ma ke ʻano he mea maka. Ma ka hana ʻana i ka waika formic me ka oxygen e hana ai i carbon dioxide a me ka wai, hiki i nā mea wahie ke hoʻohua i ka uila e hoʻohana i nā mea liʻiliʻi liʻiliʻi e like me nā kelepona paʻa a me nā kamepiula.
ʻO nā pūnaeau wahie maʻamau ka nui o nā pūnaeau wahie hydrogen a me nā pūnaeau wahie methanol. ʻO nā palena o nā pūnaeau wahie hydrogen ke kumukūʻai kiʻekiʻe o nā pahu hydrogen liʻiliʻi, ka haʻahaʻa haʻahaʻa o ka ikehu o ka hydrogen kinoea, a me ka lawe ʻana a me ka hoʻohana ʻana i ka hydrogen; ʻOiai he kiʻekiʻe ka ikaika o ka methanol, ʻoi aku ka haʻahaʻa o kāna electrocatalytic oxidation rate ma mua o ka hydrogen, a he mea ʻawaʻawa ka methanol, kahi e keʻakeʻa ai i ka hoʻohana nui ʻana. ʻO ka waiuma formic he wai ma ka lumi wela, he liʻiliʻi ka ʻawaʻawa, a ʻoi aku ka ikaika electromotive ma mua o ka hydrogen a me ka methanol, no laila ʻoi aku ka nui o nā cell fuel acid formic a me ka hoʻohana ʻana i hoʻohālikelike ʻia me ka hydrogen a me ka methanol fuel cell [9-10]. ʻO Direct formic acid fuel cell (DFAFC) he hanauna hou o ka mana lawe lima a lawe lima ma muli o kāna kaʻina hana maʻalahi, ka ikehu kiʻekiʻe a me ka mana. Hoʻololi ka ʻenehana i ka ikehu kemika i mālama ʻia i loko o ka waikawa formic a me ka oxygen i ka uila.
ʻO ka pākaukau, inā hoʻomohala ʻia, hiki iā ia ke hāʻawi ma kahi o 10 watts o ka mana mau, ʻo ia hoʻi, hiki iā ia ke hoʻohana i nā mea hana liʻiliʻi. Eia kekahi, ma ke ʻano he kumu mana, ʻoi aku ka maikaʻi o nā cell formic acid fuel i ka maikaʻi o ka hana kiʻekiʻe a me ka māmā, e like me ka plug-in charge, i hoʻohālikelike ʻia me nā pā lithium-ion. Ke oʻo nei ka ʻenehana, manaʻo ʻia e hoʻokūkū me nā pā lithium i ka mākeke lako mana liʻiliʻi. I ka manawa like, loaʻa i nā pūla wahie formic acid nā mea maikaʻi o ka non-toxic, non-flammable, ka mālama pono ʻana a me ka lawe ʻana, ka hana electrochemical, kiʻekiʻe o ka ikehu kiʻekiʻe, proton conductivity, liʻiliʻi liʻiliʻi i ka membrane exchange proton, a hiki ke hana i ka mana puka nui. ʻo ka haʻahaʻa haʻahaʻa, i makemake nui ʻia e nā poʻe loea i ka ʻoihana. ʻOi aku ka pōmaikaʻi o ka ʻoihana uila inā e lilo ia mau ʻaʻa. Me ka hoʻomohala ʻana o ka ʻenehana a me ka hōʻemi ʻana o ke kumukūʻai, e hōʻike ana ka formic acid fuel cell i kahi manaʻo maikaʻi o ka noi ʻoihana ma muli o kāna mau hiʻohiʻona o ka mālama ʻana i ka ikehu a me ka mālama ʻana i ke kaiapuni.
ʻO ka waika Formic, ma ke ʻano he huahana kemika me ka waiwai hoʻohui kiʻekiʻe i ka hana ʻana i ka carbon dioxide a me ka hana hou ʻana o nā mea waiwai kemika, he huahana hou ia o ka pōʻai kalapona a hōʻemi i nā kumukūʻai hana. I ka wā e hiki mai ana, he hopena koʻikoʻi ia i ka hana hou ʻana o ke kalapona a me ka ikehu a me ka hoʻololi ʻana o nā kumuwaiwai.
