The present invention relates to an end plate for a fuel cell stack, containing at least one channel () for the supply and/or removal of at least one reactant and/or a reaction product and/or a coolant, wherein at least a part at least of one pump () for delivering the reactants and/or reaction products and/or coolant and which is arranged in the course of the respective channel () is integrated into the end plate. The invention further relates to a fuel cell stack which contains such an end-plate.

End plate for a fuel cell stack

The present invention relates to a bipolar plate () for electrochemical systems which contains a first plate () with a first flowfield () for media distribution as well as a second plate () with a second flowfield () for media distribution. This first plate in the region of the first flow field at least in regions comprises a plane surface section () from which discrete projections () 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.
