Electrode binder solution composition for polymer electrolyte fuel cell |
摘要 |
The present invention relates to an electrode binder solution composition for a polymer electrolyte fuel cell comprising a mixture of a solvent and a nonsolvent. The electrode binder solution composition can significantly improve electrode activity by maximizing formation of a three-phase interface of catalyst, binder and fuel at the electrode catalytic layer of the polymer electrolyte fuel cell. The present invention relates to a preparation method of an electrode binder solution for a polymer electrolyte fuel cell, the electrode binder solution for a polymer electrolyte fuel cell comprising a sulfonated proton exchange hydrocarbon-based polymer and a mixture of a solvent and a nonsolvent. The present invention also relates to a preparation method of an electrode catalyst slurry comprising the steps of: mixing an electrode binder solution composition for a polymer electrolyte fuel cell with a platinum catalyst and drying the mixture; and heat-treating the dried mixture to maximize interface between the electrode binder and the catalyst.
