Hiki ke hoʻokaʻawale ʻia nā hunaola wahie imembrane hoʻololi protonnā pūnaewele wahie (PEMFC) a me nā pūnaewele wahie methanol pololei e like me nā waiwai electrolyte a me ka wahie i hoʻohana ʻia
(DMFC), ke kelepona wahie phosphoric acid (PAFC), ke kelepona wahie carbonate i hoʻoheheʻe ʻia (MCFC), ke kelepona wahie oxide paʻa (SOFC), ke kelepona wahie alkaline (AFC), a pēlā aku. No ka laʻana, hilinaʻi nui nā kelepona wahie membrane hoʻololi proton (PEMFC) imembrane hoʻololi protonHoʻohana nā cell wahie alkaline (AFC) i ka electrolyte wai alkaline e like me ka potassium hydroxide solution ma ke ʻano he proton transfer medium, a pēlā aku. Eia kekahi, e like me ka mahana hana, hiki ke hoʻokaʻawale ʻia nā cell wahie i nā cell wahie wela kiʻekiʻe a me nā cell wahie wela haʻahaʻa, ʻo ka mea mua e pili ana i nā cell wahie oxide paʻa (SOFC) a me nā cell wahie carbonate i hoʻoheheʻe ʻia (MCFC), ʻO ka mea hope e pili ana i nā cell wahie membrane hoʻololi proton (PEMFC), nā cell wahie methanol pololei (DMFC), nā cell wahie alkaline (AFC), nā cell wahie phosphoric acid (PAFC), a pēlā aku.
ʻO ka membrane hoʻololi protonHoʻohana nā cell wahie (PEMFC) i nā membrane polymer acidic wai-based e like me kā lākou electrolytes. Pono nā cell PEMFC e hana ma lalo o ke kinoea hydrogen maʻemaʻe ma muli o ko lākou mahana hana haʻahaʻa (ma lalo o 100 ° C) a me ka hoʻohana ʻana i nā electrodes metala hanohano (nā electrodes platinum). Ke hoʻohālikelike ʻia me nā cell wahie ʻē aʻe, loaʻa iā PEMFC nā pono o ka mahana hana haʻahaʻa, ka wikiwiki hoʻomaka wikiwiki, ka nui o ka mana kiʻekiʻe, ka electrolyte non-corrosive a me ke ola lawelawe lōʻihi. No laila, ua lilo ia i ʻenehana nui i hoʻohana ʻia i nā kaʻa cell wahie, akā ua hoʻohana hapa ʻia hoʻi i nā mea lawe lima a me nā mea paʻa. Wahi a E4 Tech, manaʻo ʻia nā hoʻouna cell wahie PEMFC e hiki i 44,100 mau ʻāpana i ka makahiki 2019, e helu ana i 62% o ka mahele honua; ʻO ka mana i hoʻokomo ʻia i manaʻo ʻia e hiki i 934.2MW, e helu ana i 83% o ka hapa honua.
Hoʻohana nā cell wahie i nā hopena electrochemical e hoʻololi i ka ikehu kemika mai ka wahie (hydrogen) ma ka anode a me ka oxidant (oxygen) ma ka cathode i uila e hoʻokele i ke kaʻa holoʻokoʻa. ʻO nā ʻāpana koʻikoʻi o nā cell wahie e komo pū ana me ka ʻōnaehana mīkini, ka lako mana kōkua a me ka motika; I waena o lākou, ʻo ka ʻōnaehana mīkini ka mīkini i haku ʻia me ka reactor uila, ka ʻōnaehana mālama hydrogen kaʻa, ka ʻōnaehana hoʻoluʻu a me ka mea hoʻololi voltage DCDC. ʻO ka reactor ka ʻāpana koʻikoʻi loa. ʻO ia kahi e hana ai ka hydrogen a me ka oxygen. Hana ʻia ia me nā cell hoʻokahi he nui i hoʻopaʻa ʻia, a ʻo nā mea nui e komo pū ana me ka papa bipolar, ka electrode membrane, ka papa hopena a pēlā aku.
