Change of electrochemical impedance spectra ( EIS ) with time during CO-poisoning of the Pt-anode in a membrane fuel cell

This paper focuses on the electrochemical characterisation, e.g. current-voltage-measurement and time resolved electrochemical impedance spectroscopy (TREIS) of polymer electrolyte fuel cells (PEFCs) during operation of the fuel cell with oxygen and H 2+100 ppm CO respectively. Due to the poisoning effect of carbon monoxide, the system changes its state… CONTINUE READING
