Platinum-Ruthenium (PtRu) Black represents the most advanced solution for managing "dirty" fuels or liquid alcohols. Unlike the Pt/C (supported) catalysts you’ve looked at, PtRu Black is an unsupported, 100% metal alloy designed for maximum power density and resistance to chemical poisoning.
Standard Platinum is easily "poisoned" by Carbon Monoxide (CO), which is a common byproduct of methanol oxidation or trace impurity in reformed hydrogen. Ruthenium atoms in the alloy nucleate oxygen-containing species (like $-OH$) at much lower potentials than pure Pt. These -OH groups on the Ru sites effectively "oxidize" the CO on the neighboring Pt sites into CO2, which then detaches, keeping the catalyst surface clean.
The main application field for the Pt-Ru black are: (1) Anode for Direct Methanol Fuel Cells (DMFC); (2) CO-Tolerant Anode for PEM Fuel Cells, (3) Specialized Electrolyzers.
