摘要:
The invention relates to a bipolar plate (1) for a fuel cell stack, comprising two disc parts (2.1, 2.2) which are joined to one another on the inside in a functionally tolerant manner with respect to the capability for fluid and/or gas to pass through, forming internal cavities.

The invention relates to a sorber heat exchanger wall comprising a fluid side (2) which is delimited by a fluid wall (4) and is impinged upon by a fluid releasing or absorbing heat, and a sorption side (5) that is provided with a sorption bed (6) with a sorbent (7) which accumulates a sorbate so as to absorb or release heat. In order to create a mechanically stable sorption wall that has good heat conducting and material conveying properties, the sorption bed (6) encompasses a highly heat conducting support structure (10,21) for the sorbent (7), which is connected to the fluid wall (4) in a heat conducting manner, and a hierarchical hollow space system.

摘要:
The invention relates to a heat exchanger, particularly for a heating or air conditioning unit of a motor vehicle, comprising several flat pipes which are arranged parallel to each other and are penetrated by a heat-transmitting medium. An electrically operated heating element (114) which is mounted once the heat exchanger has been soldered is assigned to at least one part of the flat pipes as an additional heating device. Said heating element (114) is fixed to the heat exchanger by means of a holding element (115The inventive heat exchanger is characterized by the fact that each heating element (114) is mounted in front of the corresponding flat pipe and parallel thereto by means of the holding element (125) which also runs parallel to the flat pipe.
