Papa Hoʻolima ʻo Graphite no nā ʻāpana wahie

1. Kumu Huahana

Ma ke ʻano he mea nui i loko o nā pūʻulu pahu wahie, ua hana pololei ʻia nā Graphite Conductive Plates for Fuel Cells mai ka graphite -maʻemaʻe kiʻekiʻe, kiʻekiʻe{1}}kiʻekiʻe. Aia ko lākou waiwai nui i ka hoʻohui pū ʻana o ka -kuʻi haʻahaʻa, ke kū ʻana o ka corrosion maikaʻi loa i nā kaiapuni ʻāka, a me ka maikaʻi o ka hoʻoili nui ʻana. Hoʻoholo pololei kēia mau hiʻohiʻona i ka mānoanoa o ka mana, ka lōʻihi, a me ka palekana o ka hana ʻana o nā pahu pahu wahie, e hoʻokō ana i nā koi kumu o ka hana kiʻekiʻe, -ola lōʻihi i hoʻoholo ʻia e ka ʻikepili nui.

2. Nā ʻāpana ʻenehana

'Ōlelo Aʻo: Hiki ke hāʻawi ʻia nā hoʻonohonoho hoʻonohonoho ponoʻī no nā ʻano pahu wahie kikoʻī (PEMFC, SOFC, AFC) a me nā pae mana, a hiki ke koho ʻia nā uhi (e laʻa, TiN, CrN) e hoʻomaikaʻi i ka hana.

3.Nā Hana Nui

ʻO ka hoʻokō maikaʻi loa: Volume resistivity Liʻiliʻi ma mua a i ʻole like me 10 μΩ·m (i hoʻāʻo ʻia e ka ASTM D4496), e hōʻemi ana i ka nalowale o ka mana kūloko a loaʻa i ka hoʻopaʻa ʻana o ka ʻoi aku ka nui ma mua a i ʻole like me 60% ma lalo o nā kūlana helu.

Kūʻē ʻAkaʻiʻo: Mālama i ka hana paʻa ma hope o 20,000+ mau hola o ka hoʻoluʻu ʻana i loko o ka solution 0.5M H₂SO₄ (35 degere ), e kūpono ana i nā koi paʻa o nā ʻōnaehana PEMFC.

ʻEnekinia Kahua Kahe Pono: Laser -kani kahe kahe (ka laula 0.8-2mm, hohonu 0.5-1.5mm) me ka hoomanawanui ana o ka emi iho a i ole like me ±0.03mm, e maopopo ana i ka mahele like ana o ka H₂/O₂ a me ka hoemi ana i ka wai hooponopono wai-e emi iho ana ka ikepili ma ka 15% ke hoohalikeia me ka oihana kahiko.

Kiekie Mechanical Pono: ʻOi aku ka ikaika compressive ma mua o a i ʻole like me 40MPa (ASTM C695), ikaika flexural ʻoi aku ka nui a i ʻole like me 25MPa, hiki ke kū i ka ikaika hoʻopaʻa paʻa (2-3MPa) me ka ʻole o ka deformation.

Haʻahaʻa Permeability: ʻAʻole i like a like paha me ka 1×10⁻⁹ mL/(cm²·s·Pa), e pale ana i ka -contamination ma waena o ka anode a me ka cathode, he mea koʻikoʻi ia no ka palekana o nā waihona mana kiʻekiʻe.

Hoʻopilikino Scalable: Kākoʻo i ka nui mai 50×50mm (micro stack) a hiki i 600×600mm (megawatt-level system), a e hana i ka mālama ʻana i ka ʻili (e laʻa, anti-oxidation coating) e hoʻolōʻihi i ke ola o ka lawelawe ʻana i nā noi mea hoʻoheheʻe oxide solid (SOFC).

 

 

4. Nā Kūlana Noi

Nā Pūnaehana PEMFC Automotive

Noi: Hoʻohana ʻia e like me nā papa bipolar i nā kaʻa kaʻa, nā kaʻa kalepa, a me nā kaʻa (no nā pahu 50-300kW);

Hiʻona Koʻikoʻi: Kākoʻo i ke ola lawelawe ʻoi aku ma mua o 300,000 km, a hoʻololi i ka -maha hoʻomaka haʻahaʻa (ʻoi aʻe ma mua o a i ʻole like me -20 degere) a me nā kūlana hana ikaika.

Hoʻokumu mana hoʻopaʻa

Noi: 1-100kW pūnaehana ikehu hoʻolaha (nā paka ʻoihana, nā kikowaena ʻikepili, nā wahi mamao);

Kiʻi Hiʻona: Low resistivity + structural stability, e hōʻoia ana i ka 99.9% loaʻa hana.

Kaʻa Moana & Kaʻaahi

Noi: -mana kiʻekiʻe wahie module modules no nā moku a me nā locomotives;

Hiʻona Koʻikoʻi: Ke kū ʻana o ka haʻalulu (10-2000Hz), ka pale ʻana i ka haʻahaʻa (95% RH), a me ke kākoʻo ʻana i ka mana kilowatt-level.

Nā Mea Mana Paʻa

Noi: 100W-5kW puʻupuʻu paʻa (nā lako kaua, nā keʻena noiʻi waho, nā lako mana pilikia);

Hiʻona Koʻikoʻi: Māmā (1.8-1.9g/cm³) me ka ʻoi aʻe a i ʻole like me 40% ka pono wahie.

Nā Pūnaehana Hui Pū ʻIa ʻOihana

Noi: Forklifts, AGVs, lako mana hoʻihoʻi no nā kikowaena ʻikepili / kahua kahua kamaʻilio, a me nā ʻōnaehana hoʻōla wela;

Hiʻona Nui: ʻOi aku ka nui a i ʻole like me 10,000-hola ola lawelawe a me nā kumukūʻai mālama haʻahaʻa.

Nā huahana pale: graphite conductive plate no ka wahie cell, Kina graphite conductive plate no nā mea hana wahie
