Grafit bipolær plade til brint

Grafit bipolære plader til brint spiller en vigtig rolle i brintbrændselsceller .

I protonudvekslingsmembranbrændselsceller er bipolære plader en af kernekomponenterne . grafit -bipolære plader er blevet et af de foretrukne materialer inden for brintenergi på grund af deres unikke egenskaber . De spiller en nøglerolle i brændselsceller som følger:

1. Conductivity and current collection. Graphite bipolar plates can be used as conductive media in battery stacks. They are responsible for connecting individual battery cells in series, collecting current and transmitting it to external circuits. Its high conductivity can ensure efficient output of electrical energy and reduce energy loss.

2. gasfordeling og reaktantudgang . Fine flowkanaler fremstilles normalt på overfladen af grafit -bipolære plader for jævnt at fordele brint og ilt, hvilket sikrer, at gass

{{0. På samme tid kan dens hydrofobicitet hjælpe vandhåndtering, forhindre væske i at blokere flowkanalen og opretholde stabil batterioperation .

The above applications of graphite bipolar plates are all based on their many characteristics. Graphite bipolar plates have stable chemical properties and can withstand the acidic environment of fuel cells. They are not easily oxidized or dissolved, and their lifespan is much longer than that of metal bipolar plates, making them suitable for long-term operation. The conductivity of graphite bipolar plates is close to that of metals, and when they come into contact with the gas diffusion layer, their resistance is extremely low, which can reduce ohmic losses and improve battery efficiency. Compared with metal bipolar plates, graphite bipolar plates have lower costs and can be processed into complex flow channels through CNC, making them suitable for large-scale production. At the same time, their excellent Højtemperaturresistens gør det muligt for dem at arbejde stabilt i brændselsceller med høj temperatur .
