Rotating Disk Electrode Techniques Designed To Simulate Fuel Cell Startup/Shut-Down Transient Conditions

摘要

A test protocol to measure catalyst durability and OER activity through multiple simulated fuel cell start-up shut-down pulses has been developed. Data for NSTF-coated glassy carbon disks coated with platinum and platinum with an overlayer of IrRu are presented. A small amount of catalyst with high oxygen evolution activity deposited on platinum leads to a significant reduction in the potential an electrode will see during a transient start-up or shut-down pulses.
