A novel high current pulse activation method for proton exchange membrane fuel cell

The performance of the proton exchange membrane fuel cell (PEMFC) is not best when it manufactured. It must be activated before can put into use. In this paper, a single-cell-based rapid activation method using high current pulses was proposed. pulse used rectangular to discharge PEMFC by adjusting peak current, period, duty cycle, and cycle times. polarization curve, electrochemical impedance spectroscopy, cyclic voltammetry tests were carried out after each cycle. results show that reaches state first whole process only needs 1 h. effectiveness verified.
