Abstract
An elastomeric material is disclosed, which is suitable, in particular, as a sealing material between the fuel cells of a fuel cell stack and the stacks as such, wherein the hybrid elastomeric material includes a hybrid elastomer with a proportion of a siloxane polymeric material and a proportion of a polyolefin elastomeric material, wherein the two materials are crosslinked with one another by addition. Further aspects relate to polyelectrolyte fuel cells, which include sealing elements made of the hybrid elastomeric material, as well as the use of the hybrid elastomeric material in a screen printing process.
