Abstract: A fuel processor (10) comprises a desulphurisation reactor (12), a catalytic partial oxidation reactor (14), a combustor (16) and a pre-reformer (18), means (20) to supply a hydrocarbon fuel to the desulphurisation reactor (12), means (24) to supply air to the catalytic partial oxidation reactor (14) and means (24) to supply air to the combustor (16). A method of operating the fuel processor for a fuel cell arrangement includes (a) supplying safe gas to the fuel cell arrangement in a first mode of operation, (b) supplying synthesis gas to the fuel cell arrangement in a second mode of operation and (c) supplying processed hydrocarbon fuel to the fuel cell arrangement in a third mode of operation.

Abstract: The present invention includes an integrated planar, series connected fuel cell system having electrochemical cells electrically connected via interconnects, wherein the anodes of the electrochemical cells are protected against Ni loss and migration via an engineered porous anode barrier layer.

Abstract: The present invention includes a fuel cell system having an interconnect that reduces or eliminates diffusion (leakage) of fuel and oxidant by providing an increased densification, by forming the interconnect as a ceramic/metal composite.

Abstract: In some examples, a fuel cell comprising a first electrochemical cell including a first anode and a first cathode; a second electrochemical cell including a second anode and a second cathode; an interconnect configured to conduct a flow of electrons from the first anode to the second cathode; and a chemical barrier. The chemical barrier may be configured to prevent or reduce material migration between the interconnect and at least one component (e.g., an anode) in electrical communication with the interconnect, where the chemical barrier includes doped strontium titanate.

Abstract: The present invention provides a method for generating a gas that may be used for startup and shutdown of a fuel cell. In a non-limiting embodiment, the method may include generating a nitrogen-rich stream; merging the nitrogen-rich stream with a hydrocarbon fuel stream into a feed mixture stream; and catalytically converting the feed mixture into a reducing gas.
