Properties and Application of Sintered Stainless Steel as Interconnectors in Fuel Cell

Abstract:

This study presents opportunities of application of sintered materials for interconnectors in low-temperature fuel cells. The task of these cell components is to provide even distribution of both fuel and oxidant. Materials for interconnectors must possess good thermal conductivity, conduct electricity and have high strength. It is also required that the material is corrosion-resistant under cell operating conditions. Due to multifunctional nature of these elements, selection of materials for interconnectors is extremely difficult. This paper presents analysis of structural properties and effect of pH level in sulphate solutions (pH = 2, 4, 6) on corrosion resistance in austenitic and ferritic sintered materials.
