Abstract: A molten carbonate fuel cell System in which the fuel cell stack(s) is (are) enclosed within a containment vessel and in which a burner exhaust is used to control the system operating pressure is described. Moreover, highly reliable, simple and low-cost differential pressure control method never affected by service interruption or troubles in control valves or other components is disclosed. Excluding differential control valves and reducing the cost by guiding the anode, cathode and vessel exhaust gases to the inlet of a catalytic burner forward the containment vessel and mixed therein so that the pressure of these gases are equal to each other, this fuel cell system guarantees dynamic pressure balancing between the vessel and reactants to prevent leakage of the reactants from the fuel cell stack and avoid an excessive differential pressure between the fuel cell and the vessel and between the anode and the cathode.
