1. A method for bonding components of a PEM fuel cell with a frame and/or amongst one another, wherefore an adhesive curable by electromagnetic radiation in the range of visible light or UV is applied to the frame and/or at least one component of the PEM fuel cell components characterized in that the adhesive is activated by the electromagnetic radiation and heated after the frame and/or PEM fuel cell the components are brought into contact; or
the frame and/or the PEM fuel cell components are brought into contact and the adhesive is exposed to the electromagnetic radiation for activating and heating;
wherein the heat reduces the viscosity of the adhesive before it is finally cured, and the heat is produced in the at least one component through application of the electromagnetic radiation, in the range of visible light or UV.
