abstract = "ETek Pt/C catalyst was used as standard materials to develop a new test protocol for fast screening durable catalyst for PEM fuel cells. Potential step (Pstep) method with the upper potential of 1.4V under low potential of 0.85V/0.60V and the potential-static (Pstat) holding at 1.4 V or 1.2V are used to degrade the catalyst. The degradation in the electrochemical surface area (ESA) for Pt/C under Pstep conditions is greatly accelerated as compared with that under other conditions. The durability of Pt/Vulcan and Pt/CNT were studied using the new protocol with the electrochemical stressing of Pstep(1.4V/0.6V), which provided the same results as those tested using conventional protocols: Pt/CNT is more durable than Pt/Vulcan. This confirms that the new protocol works well in screening catalyst in terms of durability. The new protocol can differentiate the durability of electrocatalysts by shortening the test time to several hours.",
