Electrochemical Characterization of Platinum based anode catalysts for Polymer Exchange Membrane Fuel Cell
… the tolerance of platinum based binary anode catalysts for CO poisoning from 10ppm up to1000ppm and to identify the best anode catalysts for PEMFCs that tolerates the CO fed with reformed hydrogen.

Designing interfacial structures for selective electrocatalysis
… cells stresses on the tolerance of electrode catalysts to cross-over species. A typical polymer electrolyte membrane fuel cell (PEMFC) employs a Nafion-based membrane to separate the Pt-based cathode and anode. Nevertheless, the intrinsic porosity of Nafion membranes allows reactants and …

Nano-structured platinum-based catalysts for the complete oxidation of ethylene glycol and glycerol
… carbon-carbon bonding and poisoning of the catalysts by oxidative byproducts. In order to achieve the highest efficiency, an anode needs to be engineered in such a way as to maximize activity while minimizing poisoning effects of reaction byproducts. We have engineered an anode that uses …
