Abstract:
1. A fuel cell, comprising: a first electrode; a second electrode; a membrane element disposed between the first electrode and the second electrode; at least one of the electrodes having a flow field plate; at least one flow conduit, through which a reactant can be conducted, extending in and along an outer surface of the flow field plate, the flow field plate having at least one microreaction chamber disposed in the outer surface and in flow communication with the flow conduit; said flow field plate outer surface disposed adjacent said membrane element, a catalyst disposed between at least a part of the microreaction chamber and the membrane in such a way that the catalyst has contact simultaneously with the membrane element and reactant when conducted through said at least one flow conduit; and wherein the flow field plate has at least one flow guide, and the flow guide assures an oncoming flow to the microreaction chamber and/or the catalyst, and wherein the flow guide is disposed in the flow conduit and/or the microreaction chamber.
