Haʻaheo ʻo VET-China e hoʻolauna i ka Hydrogen Fuel Cell PEM Membrane Electrode Assemblies. Hoʻohui kēia huahana hoʻololi i ka ʻenehana holomua e hāʻawi i nā mea hoʻohana i nā hoʻonā ikehu maʻemaʻe kiʻekiʻe a hilinaʻi. Ma ke ʻano he alakaʻi ma ke kahua o ka ikehu hydrogen, aia nā huahana o VET-China i ke kūlana koʻikoʻi i ka hoʻololi ʻana i ka ikehu a me ka mālama ʻana, e hāʻawi ana i nā mea hoʻohana me ka maikaʻi o ka ikehu a me ka hana kaiapuni.
Nā kikoʻī o ka hui electrode membrane:
| mānoanoa | 50 μm. |
| Nui | 5 knm2, 16 knm2, 25 knm2, 50 knm2 a i ole 100 knm2 mau wahi ili. |
| Hoʻouka ʻana i ka Catalyst | Anode = 0.5 mg Pt/cm2.Cathode = 0.5 mg Pt/cm2. |
| Nā ʻano hui electrode membrane | 3-layer, 5-layer, 7-layer (no laila ma mua o ke kauoha ʻana, e ʻoluʻolu e wehewehe i ka nui o nā papa āu e makemake ai, a hāʻawi pū i ke kaha kiʻi MEA). |
Ka hana owahie pahu MEA:
-Ka hoʻokaʻawale ʻana i nā reactants: pale i ka pilina pololei ma waena o ka hydrogen a me ka oxygen.
-Ke alakaʻi nei i nā protons: hiki i nā protons (H+) ke hele mai ka anode ma o ka membrane i ka cathode.
-Catalyzing reactions: Paipai i ka hydrogen oxidation ma ka anode a me ka hoemi oxygen ma ka cathode.
-Ke hana nei i kēia manawa: hoʻopuka i ke kahe electron ma o nā hopena electrochemical.
-Ka hoʻokele wai: mālama i ke kaulike wai kūpono e hōʻoia i nā hopena mau.
Ua hoʻomohala kūʻokoʻa ʻo VET Energy i nā mea hana kiʻekiʻe, ma o nā catalysts kiʻekiʻe a me nā kaʻina hana MEA, hiki iā ia ke loaʻa:
mānoanoa o kēia manawa:2400mA/cm2@0.6V.
mana nui:1440mW/ cm2@0.6V.
ʻO ka hale nui owahie pahu MEA:
a) Proton Exchange Membrane (PEM): he membrane polymer kūikawā ma ke kikowaena.
b) Nā Papahana Catalyst: ma nā ʻaoʻao ʻelua o ka membrane, ka mea maʻamau i haku ʻia me nā catalysts metala makamae.
c) Nā Papa Hoʻoheheʻe Gas (GDL): ma nā ʻaoʻao o waho o nā papa catalyst, hana maʻamau i nā mea fiber.
