| titleOfInvention | Method for preparing high-stability fuel cell catalyst coating slurry |
| abstract | The invention relates to the field of fuel cells, in particular to a method for preparing high-stability fuel cell catalyst coating slurry. The method for preparing the high-stability fuel cell catalyst coating slurry comprises at least two mixing and dispersing steps, wherein in the first mixing and dispersing step, a catalyst, perfluorinated sulfonic acid resin and a solvent are mixed and dispersed to obtain a first-stage mixed dispersion liquid, and in other mixing and dispersing steps, a previous-stage mixed dispersion liquid and newly added perfluorinated sulfonic acid resin are mixed and dispersed; wherein, the surfactant is added in at least one mixing and dispersing step for mixing and dispersing. The catalyst slurry prepared by the method has good dispersion stability of the catalyst, is not easy to settle, and has good performance when being applied to a membrane electrode. |
