Definitions
- the present invention relates to a catalyst for a polymer electrolyte fuel cell.
- the present invention relates to a catalyst useful for use in a cathode (air electrode) of a polymer electrolyte fuel cell.
- a platinum catalyst supporting a noble metal, particularly platinum, as a catalyst metal has been widely used. This is because platinum as a catalyst metal has high activity in promoting the electrode reaction in both the fuel electrode and the hydrogen electrode.
- the Pt—Co—Mg catalyst according to the present invention has no difference in the bonding state of Pt and the alloying phase as compared with the Pt—Co catalyst. That is, in the catalyst according to the present invention, Mg is present in the catalyst particles without being alloyed with other metals.
- magnesium itself contributes to catalytic activity. If magnesium itself has a catalytic activity, the activity should be improved if the amount added is large, but such a tendency has not been observed in the study by the present inventors. In the present invention, the amount of magnesium added is required to be suppressed to an extremely low amount as described above.
- the change in the bonding state of Pt and the presence of an alloy phase other than the Pt—Co alloy are not detected with respect to the conventional Pt—Co catalyst.
- the catalyst exhibiting a more preferable activity exhibits a peculiar difference in the peak position in X-ray diffraction in the present invention.
- This suitable catalyst is produced by a catalyst production method described later, and is a catalyst produced by supporting platinum, cobalt, and magnesium on a support, alloying them, and then eluting a part of magnesium.
- the contact time is preferably 1 to 30 hours, more preferably 2 hours or more.
- the treatment temperature is preferably 40 to 110 ° C., more preferably 60 ° C. or higher.
- the oxidizing solution treatment may be repeated not only when the catalyst is brought into contact with the oxidizing solution once, but also multiple times. Moreover, when performing acid treatment in multiple times, you may change the kind of solution for every process.
- the catalyst for a solid polymer electrolyte fuel cell according to the present invention adopts the form of a ternary catalyst in which magnesium is added to a Pt—Co catalyst, and limits the constituent ratio of cobalt and magnesium.
- the initial activity is excellent.
- a platinum catalyst was produced, and cobalt and magnesium were supported thereon.
- As the platinum catalyst 5 g (2.325 g (11.92 mmol) of platinum catalyst in terms of platinum) of 46.5 mass% platinum supported on carbon fine powder (specific surface area of about 900 m 2 / g) was prepared.
- a mixed solution of cobalt salt and magnesium salt prepared by dissolving 1.89 g of cobalt chloride (CoCl 2 ⁇ 6H 2 O) and 1.61 g of magnesium chloride (MgCl 2 ⁇ 6H 2 O) in 100 mL of ion-exchanged water was prepared. The platinum solution was impregnated with the mixed solution, and then sodium borohydride was added as a reducing agent to support cobalt and magnesium.
