Gas Diffusion Layers in Fuel Cell
1. Fast ???G Half Fewer production steps than Ballard, Toray and SGL company.
2. Lowest cost ???G
The carbon fibers of Ballard is about 35 $/kg.
The graphite fibers of Toray and SGL is 90 ???V 150 $/kg.
The raw materials of ours technical is only about 10-15 $/kg.
A carbon fiber paper manufacturing process and construction has oxidized fiber as raw material needle punched into a construction of oxidized fiber felt of weight, then impregnated in high density epoxy, hot compressed and hardened, then finally carbonization processed to yield porous carbon fiber paper with high resilience, low porosity, and flexure, and low surface resistance to be used as the substrate of porous carbon electrode in fuel battery.
