The invention discloses a fuel battery separation element, a monomer fuel battery, a fuel battery electric pile and a pole plate. The fuel battery separation element comprises an anode plate and a cathode plate, wherein the anode plate comprises an anode base plate and an anode lining plate; the anode base plate comprises an anode reaction region and an anode edge region surrounding the anode reaction region; the anode lining plate is attached to the first side surface of the anode edge region; the anode lining plate is provided with an anode flow guide passage; the cathode plate comprises a cathode base plate and a cathode lining plate; the cathode base plate comprises a cathode reaction region and a cathode edge region surrounding the cathode reaction region; the cathode lining plate isattached to the first side surface of the cathode edge region; the cathode lining plate is provided with a cathode flow guide passage; the first side surface of the cathode reaction region and the first side surface of the cathode reaction region are connected with a membrane electrode assembly of the fuel battery electric pile. By designing the pole plate of a composite stacking structure, the flow guide region of the base plate edge region can be omitted, so that the processing difficulty of the fuel battery separation element is lowered; the processing cost of the fuel battery separation element is reduced.
Description
technical field [0001] The invention belongs to the technical field of fuel cell manufacturing, and in particular relates to a fuel cell separator, a fuel cell stack with the fuel cell separator, a single fuel cell and a fuel cell pole plate. Background technique [0002] Fuel cells, especially hydrogen fuel cells, are mainly used in new energy vehicles such as fuel cell powered vehicles, buses and trucks, new energy fuel cell powered locomotives, aircraft, household distributed power supplies and other fields. [0003] A fuel cell has a stacked structure, and is generally constituted by a stack in which a plurality of single fuel cells are stacked.
