Performance enhancement of PEM electrolyzers through iridium-coated titanium porous transport layers Open
Titanium-based porous transport layers (PTL) used in polymer electrolyte membrane (PEM) water electrolyzers suffer from surface passivation (titanium oxidation), which increases the interface resistance between the PTL and electrode. For l…
