Abstract

A fuel cell, having a first electrode, a second electrode, and a membrane element, in which the membrane element is disposed between the first electrode and the second electrode. At least one of the electrodes has a flow field plate and at least one flow conduit, through which a reactant can be conducted, extends in at least one outer surface of the flow field plate. The flow field plate has at least one microreaction chamber, and the microreaction chamber is disposed in the outer surface and on the flow conduit. A catalyst is disposed on at least a part of the microreaction chamber in such a way that the catalyst has contact simultaneously with the membrane element and the inflowing reactant.
