Abstract:
A method of operating a fuel cell system includes providing a fuel cell stack containing a plurality of fuel cells and interconnects, and first and second ceramic side baffles located on opposing sides of the fuel cell stack, and applying an electrical potential to an outer surface of at least one of the first and the second ceramic side baffles, such that the electrical potential is equal to or more negative than a lowest potential of any interconnect in the fuel cell stack or electrically conductive fuel cell stack or column component.

Claim (Index 17):
The system of  claim 12 , wherein:\n the electrical potential is configured to prevent or reduce diffusion of alkali or alkali earth metal from the first and second ceramic side baffles to the fuel cell stack, which prevents or reduces corrosion of components of the fuel cell stack; the fuel cells comprise solid oxide fuel cells; the fuel cell stack is located in a first column of a plurality of columns of fuel cell stacks; the outer surfaces of the first and the second ceramic baffles face away from the first column; the first and second ceramic side baffles extend along an entire height of the first column; and the plurality of columns of fuel cell stacks are separated by inter-stack baffles.
