Bipolar plates (BPs) are key components of fuel cells. Functions of materials used for fuel cells include equal distribution of gas fuel and air, conduction of electricity between adjacent cells, heat transfer from the cell as well as prevention of gas leakage and cooldown. Moreover, the material must show particular corrosion resistance in cell’s working conditions. Due to multifunctional nature of fuel cell plates, choice of materials used for plates is immensely difficult.

This paper presents opportunities of application of a new technology of powder sintering for creation of parts for electricity and heat generators. In this research, a sintering technology was developed to obtained sintering stainless steel bipolar plates/interconnectors.

The surface roughness was measured, and an electron spectroscopy analysis (ESCA) was conducted to verify the chemical composition of the surface layer.  

The corrosion rates of the sintered materials were analysed.
