Local Current Density Prediction in a 200cm~2 PEMFC Semi-Segmented Electrode System

摘要

For PEMFC systems,experimental methods are being developed to map the current density distribution on the membrane surface.One of the best methods available to experimentalists to measure local current density is segmented electrode analysis.By electrically isolating electrode sections and measuring the current produced in each section a more accurate map of local current density can be obtained.
