During the lifetime of a polymer electrolyte fuel cell, the pore structure of the Pt/C catalyst layer may change as a result of carbon corrosion. Three-dimensional visualization of porosity changes is important to understand the origin of fuel cell p

Platinum catalyst dissolution with subsequent reduction and deposition of Pt particles in the membrane can lead to a significant loss of polymer electrolyte fuel cell (PEFC) performance. To quantify the amount of deposited platinum, a novel transmiss
