Electrooxidation of Hydrogen on Ni-Organic Metal Complex Catalysts in Acidic Media for PEMFCs

Figure 9

CV curves of Ni-organic metal complex with different substituent, in 0.5 M H₂SO₄ solution at the scan rate of 50 mV/s. From the top to the bottom, the substituent was changed from CH₃- to H- and to i-Pr-.
