The effect of platinum on carbon corrosion behavior in polymer electrolyte fuel cells

► The catalytic effect of platinum on carbon corrosion in PEFCs was investigated. ► Platinum catalyzes the carbon corrosion reaction. ► Catalytic effect depends on the upper and lower limit of the applied potential pulses. ► Formation of a platinum oxide layer has a passivating effect. To assess the...
