Sintering prevention of Ag by the addition of 2-dimensional nanosheet

The physical properties of the noble metal current-collector used for fuel cells are greatly influenced by the material porosity. Therefore, increasing the porosity of the material studies has attracted much attention. One of the most representative strategies is to use porosity additives in sintering materials. The conventional porosity additive had a three-dimensional structure of a spherical powder. In this study, porosity additive with 2-dimensional (2D) nanosheet was used to decrease the sintering density of Ag current-collector and its effect was confirmed As a 2D layered structure material, 1 nm-thick RuO2 nanosheets were used as porosity additives.
