According to the laminating method, the device is adopted, frame lamination is completed in two steps, the ultraviolet light is mainly used for curing the resin layer in thefirst step of laminating the lower frame, the hot melt adhesive layer is used in the second step, operation is easy, and the laminating effect is good.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to a fuel cell membrane electrode frame bonding device and method. Background technique [0002] A proton exchange membrane fuel cell is a power generation device that converts chemical energy into electrical energy. The fuel cell chip is a catalyst / proton exchange membrane module prepared by coating the fuel cell catalyst on both sides of the proton exchange membrane, referred to as CCM (catalyst coated membrane). The core components of a proton exchange membrane fuel cell include a fuel cell catalyst layer, a CCM, an upper frame, a lower frame, and a gas diffusion layer. Usually, the fuel cell membrane electrode manufacturing process includes catalyst coating, frame bonding, and gas diffusion layer bonding. In order to facilitate the frame manufacturing, the proton membrane exchange membrane often needs to extend to the area outside the catalytic layer, and this part is left b...

Problems solved by technology

Usually, the fuel cell membrane electrode manufacturing process includes catalyst coating, frame bonding, and gas diffusion layer bonding. In order to facilitate the frame manufacturing, the proton membrane exchange membrane often needs to extend to the area outside the catalytic layer, and this part is left blank. The area provides the bonding surface of the frame. In the prior art, the two sides of the general blank area are directly bonded to the upper frame and the lower frame respectively. It is easy to form air bubbles in the medium, resulting in defective products
