The present invention relates to bipolar plate (1) as well as to a fuel cell assembly (2). The bipolar plate comprises two outer surfaces (3a, 3b) which are electrically connected to one another, for the electrical contacting, as well as the discharge and supply of gases and/or fluids to the surfaces of the fuel cells which are adjacent to the outer surfaces. The bipolar plate comprises a frame (7) open in the central region as well as an inner part (3) arranged in the central reign, wherein the frame and the inner part are elastically connected to one another.
摘要:
The invention relates to a fuel cell system (1) which is characterized in that a fuel cell stack (2) comprised of a plurality of intermediate plates is enclosed between two end plates (3) to compress the intermediate plates. At least one end plate (3) has an end plate base (4) and a contact surface plate (5) linked therewith to electrically contact the fuel cell stack. The end plate base (4) is furthermore provided with channel structures (6) designed for a cooling circuit for cooling the fuel cell stack. The end plate is deformed in such a manner that it is capable of applying an even compression to the fuel cell stack and to balance the setting behaviour of the stack and of the end plate.

The present invention relates to a bipolar plate for fuel cells, comprising at least a shaped, at least partially electrically conductive foil (1), the bipolar plate having a channel structure (5) formed by the shaping of the foil (1), to convey reactants to electrodes of adjacent fuel cells and to carry away reaction products, and a microstructure (4) is integrated into the foil (1) to increase the rigidity of the foil (1). The invention also relates to a method for manufacturing corresponding bipolar plates.
摘要:
The invention relates to a bipolar plate (1) and to a method for the production thereof. Said bipolar plate has two plate-shaped metal sections (2a, 2b) which are connected to one another, forming a bipolar plate. Connection of the metal sections is done by means of laser beam welding.

The present invention relates to supply plate (1), a base plate for the assembly of such a supply plate, as well as a method for manufacturing a supply plate for electrochemical systems. Two base plates (2a, 2b) are thermally joined to one another using a joining agent, wherein this joining agent (3) has a lower melting point than the material of the base plates (2a, 2b). At least one first base plate (2a) comprises at least one pocket (4a) into which joining agent is filled, and subsequently the second base plate (2b) is applied onto a joining plane (F) of the first plate, and a connection of the base plates (2a, 2b) is effected by way of the impact of heat on the joining agent.

A gasket is provided that is suitable for use in connection with a cylinder head. The gasket includes a first outer plate including a compensating portion, a second outer plate including a compensating portion, and a compensating plate positioned between said first and second outer plates. Preferably, at least one of said first and second outer plates includes a bead positioned outside of, and in close proximity to, said compensation portion of said plate. The compensating plate includes a compensating element and an edge portion. In a preferred embodiment, the area between the compensating portions of said first and second outer plates defines a compensating area and said compensating element is positioned within said compensating area. If desired, the gasket may also include a spacer plate.
摘要:
A microwave combustion system is presented that can replace the conventional spark plug in an internal combustion engine. One or more microwave pulses are provided to a microwave feed in a plug that sits in the cylinder. A microwave generated plasma generated by the plug in the vicinity of a fuel mixture can provide for highly efficient combustion of the fuel-air mixture.
