The present invention relates to a contact plate for fuel cells with a coherent active area () on at least one side of the contact plate, wherein the active area () consists of a contact surface () which over the whole surface comprises a coating () of an electrically conductive, corrosion-resistant material, and of recesses () so that the recesses () form a channel structure, wherein the coating () furthermore at least in the bottom regions () of the recesses () is omitted. The invention further relates to a corresponding fuel cell or to a fuel cell stack with at least one such contact plate as well as to various methods for manufacturing such contact plates which may serve as bipolar plates as well as monopolar plates or end plates. With the contact plate according to the invention, one achieves an optimally reduced contact resistance with a minimal material expense for the coating ().

Contact plate for fuel cells

The present invention relates to a fuel cell arrangement, containing at least one bipolar plate layer () and an bonding partner&#x2014;preferably an membrane electrode assembly (MEA) (), wherein the bonding partner is bonded onto the bipolar plate layer () with a pressure-sensitive adhesive or a physically bonding adhesive, which are located on a three-dimensional sealing structure of the bipolar plate layer and/or edge region of the bipolar plate layer adjacent thereon.

Fuel cell arrangement and method of manufacturing a fuel cell arrangement

The invention relates to a gasket having at least one metallic layer, in which at least one gasket opening and at least one bead are formed, and in and/or adjacent to the bead a coating is applied as a deformation limiter, which comprises at least one filler and one bonding agent, the mass proportion of the filler being greater than the bonding agent and the filler being present in particle form, and the individual spherical particles having a small surface in relation to the volume of the particle.
