SOLID OXIDE FUEL CELL HAVING A DENSE BARRIER LAYER

A solid oxide fuel cell with a dense barrier layer formed at or near the outer surface of the top and/or bottom electrode layers in a fuel cell stack. The dense barrier layer (DBL) acts as a seal to prevent gas in the electrode layer (either air in a cathode layer or fuel gas in an anode layer) from...

Summary:A solid oxide fuel cell with a dense barrier layer formed at or near the outer surface of the top and/or bottom electrode layers in a fuel cell stack. The dense barrier layer (DBL) acts as a seal to prevent gas in the electrode layer (either air in a cathode layer or fuel gas in an anode layer) from leaking out of the stack though the outer surface of the outermost electrode layers. The use of a DBL with porous outer electrode layers reduces the amount of gas escaping the stack and minimizes the chances for leak-induced problems ranging from decreases in performance to catastrophic stack failure.
