Experimental characterization methodology for the identification of voltage losses of PEMFC: applied to an open cathode stack

The objective of this study is to describe the methodology used to isolate the main voltage loss indicators through a simple and effective treatment of a current interrupt and current sweep. The voltage loss indicators are activation polarization, mass transport, and ohmic losses. The indicators for...
