Life prediction of membrane electrode assembly through load and potential cycling accelerated degradation testing in polymer electrolyte membrane fuel cells

Accelerated degradation tests (ADTs) are commonly used to assess the durability of membrane electrode assembly (MEA) components consisting polymer electrolyte fuel cells (PEMFC) under harsh stress conditions, estimating their lifetime in actual use condition and uncovering vital mechanisms. ADTs apply mechanically, chemically, or thermally combined stressors efficiently investigate MEAs. However, for might cause biased prediction because major deterioration mechanisms MEA mixed with each other. This work proposes a method accurately predict through empirical modeling its performance potential cycle (carbon corrosion) load (electrocatalysts). To simulate operation modes cell electric vehicles, MEAs tested continuous on-off testing (24 h operating 1 break) 5000 h. Degradation patterns first modeled by model. The relationship between (potential cycle) is then closely examined environments. proposed idea has resolve critical issues identifying intermingling effects from other constituents.
