The invention concerns a vehicle wheel, comprising a body of a plastics material and at least one adapter for fastening the body to a wheel mounting, the at least one adapter having at least one protuberance which engages in a recess in the body, or, if multiple adapters are used, at least one adapter is formed such that it engages in a recess of the body over its full surface area, the adapter being arranged in such a way that, after assembly of the body on the wheel mounting, the adapter is positioned between the body and the wheel mounting, or the adapter being arranged in such a way that the body is positioned between the wheel mounting and the adapter, so that the adapter lies on the outside of the body after assembly.

Vehicle wheel

A wheel, containing a rim of a plastics material and an adapter for fastening the rim to a wheel mounting, the adapter having a protuberance which engages in a recess in the rim, or the adapter being received in a receptacle of the rime, or, if multiple adapters are used, at least one adapter engaging in a recess of the rim or being enclosed by the material of the rim, where after assembly of the rim, the adapter lies with a surface area against the wheel mounting, or the rim is positioned between the wheel mounting and the adapter, where the fastening means for assembling the rim on the wheel mounting are passed through a lead-through in the adapter and the rim made of the plastics material is connected to the adapter such that no plastics material of the rim lies in the flux of force of the fastening means.

The invention relates to a method of fabricating a bipolar plate for fuel cell stacks, wherein the bipolar plate includes a circumferential frame made of an electrically non-conductive material and further includes an inner bipolar plate region which is enclosed by the frame, is made of the electrically non-conductive material and comprises channels for gases and, if required, for coolants, said method comprising the following procedural steps: A) Inserting an electrically conductive fabric into a tool for fabricating the bipolar plate, B) Introducing the electrically non-conductive material into the tool in order to form the frame and the inner bipolar plate region (), the electrically non-conductive material extending through the fabric, C) Removing a molded bipolar plate from the tool, and D) Bending back the fabric on both sides which extends beyond the inner bipolar plate region so as to cause the fabric to cover the inner bipolar plate region made of the non-conductive material.
