Abstract

The invention relates to the technical field of cell pole plates, in particular to a hydrogen-oxygen fuel cell pole plate. A hydrogen flow field plate, an air-oxygen flow field plate and a water flow field plate are plate-shaped bodies made of graphite and resin mixtures, one side surface of each of the hydrogen flow field plate, the air-oxygen flow field plate and the water flow field plate is a plane, the other side surface is provided with a flow field, one side of the plane of the hydrogen flow field plate and one side of the plane of the water flow field plate are attached to the two sides of one gas insulation conducting film to form an anode plate, one side of the plane of the air oxygen flow field plate and one side of the plane of the water flow field plate are attached to the two sides of the other gas insulation conducting film to form a cathode plate, and the outer side surface of the water flow field plate in the cathode plate and the outer side surface of the water flow field plate in the anode plate are mutually connected. The hydrogen-oxygen fuel cell pole plate has the advantages of convenience in processing, light weight and easiness in treatment of the redundant extension part of the pole plate. The invention also provides a manufacturing method of the hydrogen-oxygen fuel cell pole plate.

Description

technical field [0001] The invention relates to the technical field of battery electrode plates, in particular to a hydrogen-oxygen fuel cell electrode plate. Background technique [0002] The conventional fuel cell plate adopts a machine-added plate or a molded plate mixed with artificial graphite and resin. The porous skeleton is made of graphite, and the resin fills the voids of the skeleton to form a complete plate. Usually, holes caused by defects in the production process will appear in the process of plate processing, resulting in plate leakage and resulting in the scrapping of the plate. [0003] The electrode plate disclosed in the existing patent (publication number CN 109546158 A) includes two metal flow field plates, and the two metal flow field plates are respectively an anode side metal flow field plate and a cathode side metal flow field plate; each The two sides of the metal flow field plate are respectively a first surface and a second surface, the first s...
