Ipawit so Pantepet

Say composite graphite bipolar plate et sakey a balon klase na bipolar plate, ya manunan uusaren ed saray fuel cell bilang importantin kabiangan. Saya so mangibibiig tan mangibunog na oxidant tan gasolina, mangikokondukta na kuryente, onsusuporta ed membrane electrode, tan mangireregula ed temperatura ed loob na reactor.

Manunan istruktura tan komposisyon

1. Matrix materials:(1) Graphite phase: natural ya graphite, pinalaknab ya graphite odino artipisyal ya graphite et mangiiter na atagey ya electrical conductivity tan chemical stability.

Saray polymer resin: singa say phenolic resin, epoxy resin, pian napaaligwas so mekanikal a biskeg tan napano so kakulangan.

Conductive filler: carbon black, carbon fiber odino metal particles pian lalon napaaligwas so konduktibidad.

2. Proseso na composite: diad panamegley na panagmolde, injection molding odino hot pressing molding, say graphite et ilalaok ed resin/filler insan ipapaabig.

Usar

Saray composite graphite bipolar plates et walaan na bentaha a singa say abeban gastos, ekselentin resistensya ed corrosion, tan mainomay ya naporma. No ikompara ed metal ya bipolar plates, epektibon napaliisan da ray kaslakan ya isyu na corrosion ya nanengneng ed kaliberliber na fuel cell. No ikompara ed saray graphite bipolar plates, mas maong so gas-tightness tan bending strength da. Niarum ni, sarayan composite ya materyales et nayarin na-optimize panamegley na eksakton pananguman ed komposisyon na resin, conductive filler ratios, tan say pangiyaplika na proseso na pananguman ed graphite odino saray additives na resin, ya mamasarag na fine-tuned performance enhancements.

Saray manunan bentaha

Benepisyo ed gastos: say gastos ed materyal et 30%-50% ya abeba nen say puron graphite plate, tan matukoy itan parad injection molding tan arum niran proseso na batch production.
Say inka-flexible na desinyo: nayarin iproseso ed ultra-thin flow channel pian napaaligwas so volume power density na fuel cell stack.
Durability: Life>5000 oras ed silong na kondisyon na fuel cell, corrosion current density<1 μA/cm².

Say ilalo ed aplikasyon

Diad tuloytuloy ya iyaaligwas na teknolohiya na enerhiya na hydrogen tan say malaknab ya aplikasyon na proton exchange membrane fuel cells, say pankaukolan na merkado parad composite graphite bipolar plates-sakey a manunan kabiangan ed sistema na fuel cell-et iilaloan ya tuloytuloy ya ombaleg. Kaleganan to, legan ya onaaralem so proseso na panaggawa tan napapawala iray makabayon conductive filler, sarayan composite materials et onaligwas so performance da, ya mangiter na mabiskeg a suporta parad komersyalisasyon na saray aplikasyon na fuel cell.
