N
owadays, methanol fuel cell systems have been
attracted research activities to investigate for
facilitating methanol oxidation reaction. One of activities
is concentrated on improving electro catalysts. Platinum
is widely used as an electro catalyst. Nickel is also due to
cost and availability, as well as good catalytic activity can
be used as an electro catalyst. In the present study, the
simultaneous presenceof nickel andplatinumas theelectro
catalyst for methanol oxidation reaction was investigated.
First for fabricating of electrodes, nickel particles was
deposited on carbon paper by cyclic voltammetry
(potential range: -0.850 V to 0.3 V vs. Ag/AgCl, scan rate
50 mV s
-1
, cycle number 30, room temperature) as the
electrochemical deposition method in three electrode
half-cell system. Then, platinum and nickel particles
simultaneously was deposited on prepared nickel layer by
cyclic voltammetry (potential range: -0.850 V to 0.650 V
vs. Ag/AgCl, scan rate 50 mV s
-1
, cycle number 30, room
temperature). At electro deposition processes the nickel
concentration was varied 10 up to 60 mM and platinum
concentration was fixed at 1 mM. The fabricated electrode
was investigated for methanol oxidation reaction in three
electrode half-cell system by the electrochemical methods
like as linear sweep voltammetry, cyclic voltammetry and
impedance spectroscopy. Accordance SEM results, the
electro catalysts are formed as nanostructure on carbon
paper. The fabricated electrode has been shown good
electro catalytic activity for methanol oxidation reaction
in alkaline media. Based on electrochemical analysis of
prepared electro catalysts, the optimum concentration of
nickel in electro deposition solution was determined at 50
mM.
