Bimetallic Nitride for Cathode
Our bimetallic nitride coating (Naco ICR) protects PEM water electrolyzer cathodes without extensive use of noble materials.
It consists of three layers. The first provides good adhesion, the second (main) nitride layer prevents hydrogen diffusion and the few-nanometer top layer ensures stable conductivity.
