A Review of Thermoplastic Composites for Bipolar Plate

2010/11/2Due to the brittle nature of graphite, graphite plates used in fuel cell stacks must typically be several millimetres thick, which add to the volume and weight of the stack. In order to solve this problem, flexible graphite was considered the material of choice for bipolar plates in PEMFC.

Fuel cell

A fuel cell is an electrochemical cell that converts the chemical energy of a fuel (often hydrogen) and an oxidizing agent (often oxygen [1]) into electricity through a pair of redox reactions. [2] Fuel cells are different from most batteries in requiring a continuous source of fuel and oxygen (usually from air) to sustain the chemical reaction, whereas in a battery the chemical energy usually
