| Popis: |
The electrical resistance of the bi-polar collector plate (both bulk and surface resistance) plays a major role in fuel cell stack performance. Typically, the plates made of graphite/polymer mixtures have lower electrical conductivity than the plates made of pure graphite. Energy Partners (EP) has developed molded graphite/composite plates with enhanced electrical conductivity. By optimizing collector plate materials, compounding and molding processes, the resistance of the molded collector/backing layer sandwich was significantly reduced. This resulted in an improvement in performance of more than 50 mV per cell at 1 A/cm2 in a 10-cell stack with 300 cm2 active area. |
