METHOD OF MANUFACTURING MEMBRANE ELECTRODE ASSEMBLY |
| 摘要 |
The method of manufacturing a membrane electrode assembly that has an electrode catalyst layer formed on a surface of an electrolyte membrane comprises (a) producing an electrode catalyst layer by drying a catalyst ink that includes catalyst-supported particles having a catalyst metal supported thereon, a solvent and an ionomer; and (b) selecting a produced electrode catalyst layer that contains an amount of sulfate ion equal to or less than a specified reference value, and manufacturing the membrane electrode assembly by using the selected electrode catalyst layer. |
