  • Heat exchanger system comprising fluid circulation zones which are selectively coated with a chemical reaction catalyst
    Patent number: 8187559
    Abstract: The invention relates to a plate (10a) intended to be integrated in a stack of plates in a heat exchanger system, the plate comprising a plurality of channels (38) distributed in rows (40), each row comprising side walls (42) arranged opposite one another and spaced apart from one another in a first direction (44), so that two directly consecutive side walls delimit one of the channels (38), the rows being arranged opposite one another and spaced apart from one another in a second direction (46) which is perpendicular to the first. Furthermore, in the fluid circulation zone (20) of the plate incorporating the channels (38), only the latter are coated with a catalyst allowing a chemical reaction.

  • SYSTEM FOR THE GENERATION OF ELECTRIC POWER ON-BOARD A MOTOR VEHICLE WHICH IS EQUIPPED WITH A FUEL CELL AND ASSOCIATED METHOD
    Publication number: 20090246568
    Abstract: A system for generation of electric power on-board a motor vehicle of the type that includes a fuel cell, a reformer for supplying the fuel cell with hydrogen-rich gas, an air-compression device, and a control unit used to control the operation of the reformer. The reformer includes a main cold-plasma reformer and an auxiliary cold-plasma reformer that are mounted in parallel upstream of the fuel cell. In addition, a control valve, which is controlled by the control unit, is mounted upstream of the two cold-plasma reformers to supply compressed air, fuel, and water vapor either to the main reformer alone or to both reformers simultaneously.
