Abstract
A method of manufacturing material suitable for the construction of a component of a fuel cell, such as a flow field plate or electrode. Uncured resin impregnated flexible graphite sheet is ground into particles. Without re-expanding the particles, and without adding further resin to the particles, the particles are molded into the form of the desired material. The material is then cured. Additives may be mixed with the particles to improve the properties of the material.
