Abstract

The invention relates to a core component with a sealed frame and a membrane electrode prepared by using the core component. A method for preparing the membrane electrode of the core component with the sealed frame is characterized in that a sealed frame material coated with a sticky glue layer on one surface thereof at the normal temperature is adopted, and a strengthened underlay is attached to the other surface thereof. The sealed frame is overlapped on two surfaces of an ion exchange membrane under the condition that one surface of the ion exchange film is supported. Then, an active area of the ion exchange membrane is coated with a catalyst, and the core component (CCM) with the sealed frame is prepared, and then carries out the hot pressing with a gas diffusion layer with a micropore layer and a gas diffusion layer (GDL), so as to prepare the membrane electrode (MEA).

Description

technical field [0001] The invention relates to a core component with a sealing frame and a membrane electrode prepared therefrom. Background technique [0002] Ion-exchange membrane fuel cells (PEMFC) have the advantages of high power density, high energy conversion efficiency, low-temperature start-up, and environmental friendliness. Today, it has become one of the hot spots of international high-tech competition. Membrane electrode (MEA) is the most critical component of ion exchange membrane fuel cell power generation. It is mainly composed of two porous gas diffusion layers with good conductivity and an ion exchange membrane sandwiched between them. A large number of finely dispersed catalysts that can initiate electrochemical reactions are evenly distributed on the interface on both sides. Hydrogen / methanol and oxygen / air are evenly dispersed to the surface of the catalyst through the opposite gas diffusion layer to undergo electrochemical reactions, and the electroch...
