摘要

Vehicle component comprises a thermoelectric layer (3) formed as part of an electrical heating and/or cooling device and/or device for producing electrical energy from heat arranged on a wall of the component. An Independent claim is also included for an exhaust gas device containing the above component. Preferred Features: An insulating layer (2) and the thermoelectric layer (3) are arranged on the inner side of the wall, the insulating layer being formed as an intermediate layer made of ZrO2 and/or Al2O3. The thermoelectric layer is made of Mg2Si and/or beta -FeSi2.
