Abstract

Composite materials based on a thermosetting binder and thermally expanded graphite with a filler content of 50-70% were obtained by hot pressing. The influence of the method of introducing the filler into the composite on its physical, mechanical and electrochemical characteristics has been studied. Materials obtained by mixing air-dry components are characterized by high electrical conductivity (up to 195 S/cm) and strength properties (more than 25 MPa), low interfacial contact resistance (less than 10 mΩ cm2) and a corrosion current not exceeding 1 μA/cm2, which will allow ensure high efficiency of energy conversion in PEM FC.
