Corrosion analysis of graphite sinter as bipolar plates in the low-temperature PEM fuel cell simulated environments

Abstract The article presents the results of research and an analysis possibility using sinters made graphite powder as a material dedicated to production bipolar plates for low-temperature fuel cell. use metallurgy technology allows materials that meet requirements cell elements construction closing single (bipolar or monopolar plates) interconnectors. morphological chemical powder, microstructural produced sinter, functional properties, i.e., porosity, roughness, corrosion resistance under operating conditions cell, were performed. sinter was tested in anodic (in corrosive environment saturated with hydrogen) cathodic oxygen). Graphite show high resistivity both environments, which serial covers cells.
