    摘要: The present invention relates to a bipolar plate (1) for electrochemical systems which contains a first plate (2) with a first flowfield (2a) for media distribution as well as a second plate (3) with a second flowfield (3a) for media distribution. This first plate in the region of the first flow field at least in regions comprises a plane surface section (4) from which discrete projections (5) distanced to one another project arranged in a distributed manner. Furthermore a method for manufacturing this bipolar plate is suggested as well as an electrochemical system which contains this bipolar plate. According to the invention it is possible in an inexpensive manner to manufacture a bipolar plate which permits the construction of fuel cells functioning with a low peripheral consumption (pumps, compressors) and which are safer with regard to their operation.

    摘要: The present invention relates to a contact plate for fuel cells with a coherent active area (11) on at least one side of the contact plate, wherein the active area (11) consists of a contact surface (2) which over the whole surface comprises a coating (4) of an electrically conductive, corrosion-resistant material, and of recesses (3) so that the recesses (3) form a channel structure, wherein the coating (4) furthermore at least in the bottom regions (5) of the recesses (3) 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 (4).
