Use of TiAlxNy0z Deposited by Reactive Sputtering as a Coating Materials on Stainless Steel for Fuel Cell

Terry Alford (Inventor)

Research output: Patent

Abstract

Carbonate Fuel Cells (CFCs) are often used as backup power generators, including uses in hospitals, large offices, and other uses which require large amounts of power. The typical CFC includes an electrolyte contained between an anode electroplate and a cathode electroplate. The electroplates are mounted to or supported by separator plates, usually made of stainless steel.High temperatures are necessary to maintain the electrolyte, usually a carbonate salt mixture, in a molten state. The molten form is necessary for an efficient chemical reaction to create free electrons. However, the high temperature conditions, in combination with the chemical reactions, create a very corrosive environment. The corrosion limits the life of the fuel cell.Placing a layer of TiAlNO on the protector plates can increase the separator plates' life span in excess of 40,000 hours between failure or required maintenance.
