Abstract

A fuel cell with an improved electrocatalyst and a method of pretreating a fuel cell to improve the electrocatalyst are disclosed. The method of pretreating a fuel cell comprising an anode catalyst comprising platinum supported on a niobium-doped titanium oxide support comprises holding the fuel cell at a potential of about 1.45V for at least about 2 hours. In another embodiment the method of pretreating the fuel cell comprises potential cycling the fuel cell from about 1.0V to 1.4V for at least about 700 cycles, or for at least 2000 cycles or 3000 cycles. It was found that by pretreating the fuel cell as described above, the hydrogen reduction reaction electrocatalytic activity of the anode catalyst is maintained while the oxygen reduction reaction electrocatalytic activity is selectively reduced.
