A bipolar plate cooler module for fuel cell stacks has complementary grooves for sealing material on both sides of each pole plate, an integral, injection moulded sealing element to fix and seal the plates together, and a compressible, conductive element b...

A plate cooler module for a fuel cell stack with cathode and anode side pole plates (7a, 7b) whose faces (in direct electrical contact) form cooling surfaces enclosing a coolant distribution structure consisting of ducts (19) and surrounded by a seal (21),...

Following mixing and before firing with hydrogen as a protective atmosphere, a compressed profile (1) is roller-compacted continuously. It comprises green (unfired) carbon material (pyrolytic carbon plus additives and binder) with thin metallic conductors ...

The composite material consists of a matrix of burnt carbon with heat-conducting bindings and layered thin electrical conductors within it. The material has a density of less than or equal to 2. 3g/cm3> and a mean specific electrical resistance parallel to...

The multilayered composite material for combustion chambers or nozzles of flying craft comprises an inner layer consisting of fiber reinforced ceramics whose matrix contains phases of carbon and/or phases of silicon carbide. The outer layer of the material...

This invention relates to electrode substrates for electrochemical cells, particularly low-temperature fuel cells, and processes for their production. Low-cost carbon fiber paper structures are used as precursor for preparation of an all-carbon product tha...

Contact plate in an electrochemical cell having electrodes comprises an injection molded basic body having a through plane conductivity of at least 20 S/cm, and formed of a plastic-graphite composite having a thermoplastic plastic component. The body has a...

Bipolar plates (516) for electrochemical cells, particularly low-temperature fuel cells, with surface modification to enhance through-plate conductivity, processes for improving the surface properties of those bipolar plates, and fuel cell assemblies made ...

The device has a carbon sliding body (1), a bearer (3,3') and an electrical conductor (4). The bearer and electrical conductor are separate components, whereby the material of the bearer is selected from carbon-reinforced compound materials and metals and ...
