Preparation of dual catalyst electrode via hybridization of Pt-C and Pt-ZrO2 synthesized by sol-gel process for self-humidifying PEMFC |
| 초록 |
Hydrophilic ZrO2 nanoparticles are prepared by sol-gel process to which Pt nanoparticles are deposited. During sol-gel process, acetic acid and ammonia are added to control the particle size and well-defined ZrO2 nanoparticles are finally obtained through the calcination at 600ºC for 4 h under air flow. Platinum nanoparticles is deposited on the zirconia by Pt salt reduction and characterized. ZrO2 and Pt-ZrO2 nanoparticles are identified by XRD, SEM, EDS and XRF analyses. Dual catalyst layers comprising Pt/C and Pt-ZrO2 are prepared and adopted to the membrane electrolyte assembly for self-humidifying PEMFC. Elecrochemical and physical properties are analyzed and the cell performance is evaluated and discussed. |
