Embodiment Construction

[0024] The specific embodiments of the present invention will be described in further detail below in conjunction with the drawings and embodiments. The following examples are used to illustrate the present invention, but not to limit the scope of the present invention.

[0025] Such as figure 1 , figure 2 An integrated electrode with air passages includes an electrode body 1. The difference lies in that there are several air passage plates 2 stamped and formed on the electrode body 1. In order to achieve contact with the battery or metal parts, A contact surface 4 is formed on the top of the airway plate 2. Moreover, relying on the stamping and forming, a certain gap gap is provided between the air passage plate 2 and the electrode body 1, and the gap gap constitutes an air passage structure. At the same time, in order to realize the smooth conduction of the airway structure, three edges of the airway plate 2 are disconnected from the electrode body 1, or at least two edges o...

Abstract

The invention relates to an integrated electrode with an air channel. The integrated electrode comprises an electrode body; a plurality of air channel plates are formed on the electrode body in a stamping mode; the tops of the air channel plates form a contact surface; an air channel structure is formed between each air channel plate and the electrode body; and three edges of each air channel plate are disconnected from the electrode body, or at least two edges of the air channel plate are disconnected from a motor body. Therefore, the air channel plates are formed by stamping and etching processing does not need to be used, so that batch processing is facilitated, the manufacturing cost is low, and the processing efficiency is high. The airway plates can have a convex effect with respectto the electrode body, and each has opposite planes, so that the air channel plates are conveniently in contact with a battery piece or a metal piece. An arc bending is arranged, so that the air channel plates have certain elasticity, so that the whole electrode has certain compressibility in the direction. And due to the fact that the plurality of air channel plates are distributed according to requirements, the ventilation area is enlarged, and gas can better react with the battery piece.

Description

Technical field [0001] The invention relates to an electrode accessory, in particular to an integrated electrode with an airway. Background technique [0002] Energy and the environment are important issues facing all mankind. Considering the requirements of sustainable development, fuel cell technology is attracting the attention of energy workers. In the design of SOFC fuel cell stacks, the power and gas distribution of the cells are generally carried out separately. Different technologies are used for the cathode and anode to take the electrode. The cathode uses the precious metal silver mesh structure that is not easy to oxidize, the anode uses the foamed nickel structure, and the cell gas distribution (for the cell anode to supply the anode reaction gas such as hydrogen, and for the cell cathode to supply air). The airway plate is completed. [0003] At the same time, the earliest anode directly used foamed nickel to distribute gas, and the cathode was added with a layer of a...
