(JP11176460-A)   NOVELTY - A turbulator includes at least one porous bed having a leading face admitting a mixture into a porous bed from an input chamber. The porous bed also has a trailing face through which the mixture exits the porous bed and a mixing zone intermediate the leading and trailing faces for intimately mixing the effluents in the mixture. The mixing zone defines several tortuous channels through which the mixture passes.    USE - In catalytic combustor that is integrates with a fuel cell system. The combustor is fueled with hydrogen-containing anode effluent and oxygen-containing cathode effluent, and includes device at its input end to induce intimate mixing of the anode effluent with the oxygen-dilute cathode effluent.    ADVANTAGE - Ensures efficient and uniform burning of the hydrogen on the catalyst bed without the creation of 'hot spots' or significant temperature differences throughout the catalyst bed    (JP3088099-B2)   NOVELTY - A turbulator includes at least one porous bed having a leading face admitting a mixture into a porous bed from an input chamber.
