Abstract

The invention relates to a highly flexible electrically conductive layer material containing non-metal powder, especially carbon, as conductive component and to a method for the production thereof. Low-specific electrical resistance, high mechanical stability and flexibility can be obtained while using cost-effective materials and a simple production method. According to the invention, the layer material is characterized in that the contact points between the conductive non-metal particles are well defined and in that coatings of binding polymers are avoided. This is achieved in that the contact points are formed before adding the essential binder by pressing or rolling. The binder is added subsequently in the form of a liquid, hardenable plastic material that fills in part of fully the pores of the layer material. In order to improve mechanical properties, the layer material may contain fibers, e.g. carbon fibers. The layer material can be used for shielding against electromagnetic interferences, as mechanical reinforcement for gas diffusing electrodes or as bipolar plates to separate reactants in electrochemical cell stacks, especially PEM fuel cells.
