Degradation Mechanism of Polymer Electrolyte Fuel Cells

Durability is one of the most important issues in commercialization of polymer electrolyte fuel cells (PEFCs). Hydrogen peroxide formation, which is formed electrochemically or chemically during operation, is one of the potential deteriorating factors of PEFCs. It was found that hydrogen peroxide is intrinsically formed as a 2-.
