Manufacturing of the carbon/phenol composite bipolar plates for PEMFC with continuous hot rolling process

摘要

The bipolar plate is a major component determining the cost, volume and performance of a PEMFC (Polymer Electrolyte Membrane Fuel Cell) stack. Carbon composite/epoxy has been considered to be a potential material for bipolar plates due to its good mechanical properties, electrical conductivity and corrosion resistance. However, the long curing time of the epoxy matrix under high pressure remains an obstacle for mass production.
