Low platinum loading electrospun electrodes for proton exchange membrane fuel cells
… fuel cell tests. However, sputtered platinum electrodes performed significantly worse than commercial thin film electrodes due to high activation and concentration voltage losses. Cyclic voltammetry and rotating disc electrode experiments were performed in order to evaluate the influence of …

Rapid screening of PEM FC cathode catalysts
… first system developed was the 64 channel pin electrode array, using liquid electrolyte. The developed method improved both the quality and reproducibility of the data and has been used to rank catalyst samples, as well as to optimize loadings and the preparative methods of inks. The second …

CuAg bimetallic nanoparticles for the electrochemical reduction of carbon dioxide
… reactors, a batch reactor with a gas diffusion electrode, and a rotating disc electrode reactor. It was found that catalysts synthesised in the absence of HDA had a phase-separated atomic arrangement, forming islands of Cu and Ag. On the other hand, synthesis conducted in the presence of HDA …

Correlative ex-situ analysis and operando ellipsometric investigation during oxygen evolution reaction of mesoporous iridium oxide model catalysts
… analytical techniques. For example, standard rotating disc electrode experiments are performed to study the impact of the catalysts structure on electrochemical processes, but do not provide any information about changing material properties during the experiment. Ellipsometry is a very …
