摘要： A catalytic combustor for a gas turbine includes a stack of metal strips, each strip having an inlet end and an outlet end. The inlet ends of both sides of the strip are uncoated, to limit the temperature and maintain rigidity of the strip at the inlet end. In one embodiment, both sides of the strip have a light-off band, coated with catalyst, and adjacent to the uncoated inlet band. One side of the strip (Side A) also includes at least one combustion band, while the other side (Side B) has no corresponding coated band. The strips are arranged such that Side A of a given strip inside the stack faces Side A of an adjacent strip, and Side B of a strip inside the stack faces Side B of an adjacent strip. The resulting structure prevents overheating of the combustor, maintains its rigidity, and reduces the pressure drop through the combustor.

摘要： A heat exchanger is made from a single piece of metal foil. The foil is coated with catalyst, corrugated with herringbone or skew corrugations, except along narrow flat areas near its edges, and folded back and forth upon itself. The folded metal structure is blocked off, except at regions near the flat areas, and enclosed in a container. A first gas stream flows into one set of folds, in a path which includes the flat areas and the channels formed by the corrugations. A second gas stream similarly flows into the other set of folds. The two streams are in thermal contact, but do not mix. The heat exchanger is especially useful in operating a catalytic fuel reformer, or in other applications involving catalytic processes. Alternative embodiments use straight corrugations to create straight channels that minimize the pressure drop through the heat exchanger.

摘要： A compact steam reformer produces hydrogen to power a fuel cell, such as can be used in a vehicle. The steam reformer includes a first channel, at least partly coated with a steam reforming catalyst, and a second channel, at least partly coated with a combustion catalyst, the channels being in thermal contact with each other. Heat from the combustion is used in the steam reforming reaction. In another embodiment, the gas streams feeding the reforming and combustion channels pass through a valve which reverses the gas streams periodically. The combustion channel becomes the reforming channel, and vice versa, so that carbon deposits in the former reforming channel are burned off. This arrangement enables the reforming reaction to continue indefinitely at peak efficiency.
