- Abstract
The polymer electrolyte fuel cells are electrochemical devices that can produce electricity, water, and heat through chemical reactions of hydrogen and oxygen. This manuscript focuses on one detailed state of degradation, called as Membrane Chemical Stability and Metrics. The Accelerated Stress Test under study was standardized by the Department of Energy. Recent advancements in the study of degradation are related to achieving three important objectives: increasing system specific power, reducing system cost, and improving system durability to make fuel cell technology more commercially accessible. The manuscript briefly introduces the Proton Exchange Membrane fuel cells, passing through the mention of the targets proposed by 2025 by... (More)
The polymer electrolyte fuel cells are electrochemical devices that can produce electricity, water, and heat through chemical reactions of hydrogen and oxygen.

Recent advancements in the study of degradation are related to achieving three important objectives: increasing system specific power, reducing system cost, and improving system durability to make fuel cell technology more commercially accessible. The manuscript briefly introduces the Proton Exchange Membrane fuel cells, passing through the mention of the targets proposed by 2025 by the Department of Energy. Next, also addresses the latest advancements and evidence of degradation factors in the main layers of fuel cells, including the Perfluorosulfonic Acid Membrane, the Catalyst Layer, and the Gas Diffusion Layer. Finally, it includes a brief analysis of external factors such as temperature, relative humidity, and the stoichiometry ratio's influence on understanding the impact on fuel cell performance.
