Abstract
An electrically conductive adhesive is disclosed for bonding anode and cathode flow field plates together for use in fuel cells. The adhesive formulation comprises epoxy methacrylate resin and non-fibrous carbon particles but little to no carbon fibres. The adhesive provides suitable strength, bond gap, conductivity and other properties, particularly for flow field plates made of flexible graphite, carbon, or metal.
