SANDVIK has released a new interconnector material made from optimum stainless steel combined with tailor-made surface coatings, suited for fuel cell assembly.
The pre-coated Sandvik Sanergy HT is said to minimise chromium evaporation and extend operational life. The coating is applied via the company’s Surface Technology in a continuous process.
According to the company, the material has good processing and forming characteristics, and is also gas tight to allow the use of thin plates within the fuel cells.
The manufacturer claims it carefully controlled the steel strip’s chemical composition, and added molybdenum and niobium to enhance the materials’ high temperature strength and oxidation resistance. The interconnector is fully recyclable.
