Voltammetry study on hydrogen peroxide fuel cell
« on: August 17, 2019, 08:06:12 PM »
Hello all,

I'm an electrical engineering student doing chemistry so please be too harsh  :P.

I'm trying to follow this paper https://pubs.rsc.org/en/content/articlehtml/2014/ra/c4ra00874j on hydrogen peroxide fuel cell. In the paper, the authors used linear potential sweep voltammetry to get the Current-potential and current-power curve of the cell.

My questions are:
1) Why use potential sweep on the electrodes instead of measuring the potential and current directly with a multi-meter? My understanding of voltammetry is the sweep potential causes redox reactions at the cathode and the surface activities of the cathode "alone"  can be characterized, but now there is a anode (cathode-anode pair).
2)  For the apparatus, is the anode acting as the counter electrode and the cathode acting as the working electrode? I guess is yes...

I apologize in advance if the questions are very basic.

Thank you!!
