NeoGraf GRAFCELL® FFP-300 SERIES Flow Field Plate Graphite
Categories:	Carbon; Graphite
Material Notes:	Manufactured from expanded natural graphite, GRAFCELL® Flow Field Plate (FFP) components retain a continuous graphitic phase. This phase continuity, combined with a low contact resistance, provides electrical and thermal properties in comparison to both synthetic graphite composite and metallic fuel cell components. The thermal diffusivity of GRAFCELL® FFP SERIES products is 8-12 times higher than composite materials and 33 times higher than stainless steel. GRAFCELL® FFP SERIES products have played a critical role in improving fuel cell power density and performance for over 10 years. With over two million kilometers of road experience in car and bus applications annually, GRAFCELL® FFP SERIES continuous phase flow field plates have replaced synthetic graphite as the premier material for PEM fuel cells. Formerly a product of GrafTech.
