Abstract
An arrangement is disclosed for reducing use for safety gases in a high temperature fuel cell system, each fuel cell in the fuel cell system including an anode side, a cathode side, and an electrolyte between the anode side and the cathode side. The fuel cells can be arranged in fuel cell stacks. The fuel cell system can include a fuel cell system piping for reactants, and feeding of fuel to the anode sides of the fuel cells. Electrical anode protection can be achieved by supplying a predefined voltage separately to at least two fuel cell stacks or groups of fuel cell stacks to prohibit oxidation of anodes.
