Preparation Process of CCM Method
Preparation Process of CCM Method CCM (Catalyst Coated Membrane) method, namely catalyst coating membrane method, is a method of directly coating the catalyst on both sides of the proton exchange membrane to form a catalytic layer. Its main preparation process is as follows: 1. Material preparation Proton exchange membrane: Select a proton exchange membrane with high proton conductivity, good chemical stability and mechanical strength, such as perfluorosulfonic acid membrane. Pretreatment [...]
