I've studied about stability testing in fuel cells which is done by potential cycling keeping a current constant value. Like stability testing in CH-instrument using technique chronopotentiometry for 10,000 cycles at anodic and cathodic current 0.0001amp for voltage range 0V to 1V. But a lot of research papers show the Accelerated stress tests with square wave cycling between two potential points with time lap also. I'm unable to find the name of the technique or may be it is not available in CH-Instrument. Please help.
