Fabrication of PtRu/C catalyst ink slurry for large-scale decal transfer method with high performance PEMFCs |
| 초록 |
The large-area membrane-electrode assembly (MEA) has been fabricated using the decal transfer method with a methanol (MeOH)-based PtRu/C catalyst slurry. The stability of slurry dispersion is important when using a large-area decal transfer method to ensure the integrity of the electrode. In order to prepare stable and well dispersed catalyst slurry, a suitable solvent for the PtRu/C catalyst should be selected. We found that the MeOH-based PtRu/C slurry dispersion showed the best stability and dispersibility of catalyst-ionomer agglomerates. It was also confirmed that the MeOH-based slurry has the most suitable characteristics for coating the slurry on the substrate film. The decal technique-based MEA using this slurry showed excellent performance when compared with the spray method-based MEA. Furthermore, the large-area PtRu/C MEA with an active area of 51.84 cm2 was fabricated and excellent performance was realized even when a reforming gas was used. |
