STRUCTURE FOR PREVENTING VORTEX FLOW IN STACK OF FUEL CELL

摘要

Provided is a structure for preventing vortex flow in a fuel cell, which minimizes generation of vortex in the fluid flowing through a channel in a bipolar plate, and thus increases electrochemical reaction efficiency of air with fuel. The structure for preventing vortex flow in a fuel cell comprises: a membrane electrode assembly(MEA) having a cathode and an anode on both surfaces thereof; bipolar plates(51) disposed in contact with both surfaces of the MEA and having channels(56,57) through which fuel or air flows on the contact surface with the MEA; and guide grooves(G) formed in the channels of the bipolar plates for stabilizing the flow of fluid.
