preparation example 1

[0070] Preparation Example 1: Preparation of Supported Catalyst (Using Microwave Irradiation)

[0071] RuCl containing 40mg Ru 3 The precursor was dissolved in 25 mL of ethylene glycol (EG), and the resulting solution was added to a slurry in which Black Pearls 2000 (Cabot, BP-2000) was dispersed in 25 mL of ethylene glycol (EG), thereby obtaining a mixed solution. Then, the mixed solution was ultrasonically treated for 30 minutes, and then microwaves having an irradiation output of 700 W were irradiated thereto for 90 seconds, and the temperature was cooled to room temperature. Then, the Ni(NO 3 ) 2 A solution was added to the cooled solution, thereby preparing a mixture solution.

[0072] Then, Na containing 10 mg Se 2 SeO 3 Aqueous solution with 100 mg solid NaBH 4 After mixing, the mixture was allowed to stand for 30 minutes, thereby obtaining a solution in which Se was reduced. When the solution turned dark red, the dark red solution was added to the solution con...

[0074] Preparation example 2: the manufacture of supported catalyst (comprising with NaBH 4 reduction)

[0075] RuCl containing 40mg Ru 3 Dissolve in 4 mL of water, and then add this solution to 25 mL of a solution containing ethanol and water in a volume ratio of 4:1.

[0076] Then, carbonaceous carrier Black Pearls 2000 (Cabot, BP-2000) was added thereto, thereby obtaining a mixed slurry.

[0077] The mixed slurry was ultrasonically treated for 30 minutes, then 10ml of 0.2M NaBH was added dropwise thereto 4 aqueous solution.

[0078] The resulting mixed slurry was stirred for 1 hour, and then Ni(NO) comprising 5 mg Ni dissolved in water was added thereto. 3 ) 2 solution, thereby obtaining a solution containing Ru and Ni.

[0079] Then, Na containing 10 mg Se 2 SeO 3 Aqueous solution with 100 mg solid NaBH 4 After mixing, the mixture was allowed to stand for 30 minutes, thereby obtaining a solution in which Se was reduced. When the solution turned dark red, th...

[0081] Preparation Example 3: Preparation of Supported Catalyst (Using Microwave Irradiation)

[0082] Co produced in the same manner as in Preparation Example 1 x Ru y Se z / C, except when using Co(NO 3 ) 2 solution instead of Ni(NO 3 ) 2 out of solution. in Co x Ru y Se z / C, the weight ratio of Co:Ru:Se is 10:80:20 and the loaded Co x Ru y Se z 50%.

Description

technical field [0001] One or more embodiments of the present invention relate to a supported catalyst for a fuel cell, a manufacturing method thereof, and a fuel cell including the supported catalyst. Background technique [0002] A fuel cell generates an electromotive force according to a cell reaction in which hydrogen reacts with oxygen to generate water. Hydrogen is obtained by reacting a source material, such as methanol, with water in the presence of a reforming catalyst. According to the electrolyte and fuel, such fuel cells can be classified into polymer electrolyte membrane fuel cells (PEMFC), direct methanol fuel cells (DMFC), phosphoric acid fuel cells (PAFC), molten carbonate fuel cells (MCFC) and solid oxide fuel cells fuel cells (SOFCs). [0003] Also, fuel cells have various operating temperatures and components depending on the electrolyte used therein. [0004] Typically, PEMFCs and DMFCs include a membrane electrode assembly (MEA). The MEA includes an ...
