Effects of Metal Ions Derived From Core-Shell Electrocatalyst on Cell Durability

impregnation was examined by power generation tests. The Al 3+ impregnation compromised the durability, whereas Cu 2+ improved it when the impregnated concentration was 1000 ppm. In the current study, 10% Cu 2+ , Al 3+ , Fe 2+ , Ni 2+ , Ag + , and Pd 2+ were impregnated to investigate magnified effect of metal ions in three durability tests. The cell and membrane durability was evaluated by analyses and was discussed based on oxidation reduction potential (ORP).
