| 摘要 |
The present invention relates to a nanocomposite catalyst for polymer electrolyte membrane fuel cells (PEMFCs). The present invention provides a nanocomposite catalyst that has a metallic catalyst material supported on a graphene nano single sheet (GNS) and has carbon black (CB) introduced to prevent the restacking of the GNS; and a manufacturing method thereof. Therefore, a polymer electrolyte fuel cell with excellent performance can be manufactured as the specific surface area of the GNS can be kept very high. |
