    摘要: An electrical contacting device for a fuel cell assembly comprises a printed circuit board comprising electrically conductive regions for providing reliable electrical contact with fuel cell components of the fuel cell assembly. Preferably the printed circuit board is flexible. The contacting device may be used, for example, for monitoring cell operating parameters like current or voltage, for short circuiting or by-passing individual cells or for directing signals to the stack.

    摘要: An electrochemical cell stack comprises a plurality of membrane electrode assemblies interposed between pairs of separator plates. The stack comprises adhesively bonded layers. Preferably each membrane electrode assembly is adhesively bonded to the adjacent pair of separator plates. The adhesive bond between the plate and membrane electrode assembly preferably provides a substantially gas and liquid-tight seal around the perimeter of the electrochemically active area of the membrane electrode assembly and around any fluid manifold openings formed therein. Alternatively, or in addition, adjoining pairs of separator plates in an electrochemical cell stack may be adhesively bonded together. Such pairs of adhesively bonded plates may define cooling spaces between neighboring cells. Stacks comprising a plurality of individual cell modules may be formed, each module comprising a membrane electrode assembly bonded to a pair of separator plates.

    摘要: An apparatus for measuring the voltage of a plurality of voltage sources mounted in a stack includes a plurality of contact units, each having a plurality of electrical contacts mounted therein, for voltage tapping of the voltage sources. The contact units are held in a support module, arranged side by side along a longitudinal axis. An evaluation unit is coupled in communication with the contacts contained in the contact units, either directly, or via an intermediate unit that includes addressing and processing capability. The number of contact units that are arranged in the support module is variable in accordance with the number of voltage sources contained in the stack, and the contact units themselves are movable longitudinally within the support module to accommodate spacing of the voltage sources in the stack.

    摘要: A two-stage evaporator unit converts a liquid reactant mass flow adjustable as a function of a load presetting into a gaseous reactant mass flow. The liquid reactant mass flow is at least partially evaporated in the first stage by a heat-exchange medium, and, if appropriate is completely evaporated and subsequently superheated in the second stage. The evaporator unit is formed by the alternating stacking one on the other of foils having heat-exchange channels and by foils having reaction channels that, in each case, have at least one first and one second stage integrated in one foil. The first stage is configured as a channel with a minimized cross-sectional area which is directly connected to the inflow conduit. The first stage is operated at high coefficients of heat transmission. The total cross-section of the reaction channels in the second stage increases in the flow direction.
