... poisoning by reformed hydrogen fuel. We analyze the characteristics of the CO poisoned anode of the PEFC at 80 ° C including CO adsorption and electro-oxidation behaviors by current-voltage ( I ‐ V ) measurement and electrochemical impedance spectroscopy (EIS) to find parameters useful for the diagnosis. I...

...Damiano Di Penta; Karim Bencherif; Michel Sorine; Qinghua Zhang This paper proposes a reduced fuel cell stack model for control and fault diagnosis which was validated with experimental data. Firstly, the electro-chemical phenomena are modeled based on a mechanism of gas adsorption/desorption...

... components: gas mixing and humidification part, oven with temperature controlled cell, and the electronic load (Fig. 1 ). In all experiments with hydrogen chloride and hydrogen sulfide perfluoralkoxy-Teflon (PFA) tubes were used to prevent adsorption and reaction of these gases. Only the direct supply...

...Jérôme Roques; Alfred B. Anderson A quantum mechanical study of O 2 and OOH adsorption on Pt(111) and on a Pt monolayer on Pt 3 Cr ( 111 ) is presented. The calculated adsorption energies are used to predict the reversible potential for O 2 reduction to OOH(ads) on these surfaces. The resulting...
