Local Study on Hydrogen and Hydrogen Gas Bubble Formation on a Platinum Electrode

Hubert Girault, Andreas Stephan Lesch, Alberto Battistel, Christopher Raymond Dennison

This work investigates the effect of current density on the hydrogen gas bubble formation during electrolysis on a platinum electrode. Local detection of bubble evolution was performed electrochemically by using a hydrogen-collecting microelectrode placed ...
