The bubbling gas electrode technique for studying electrochemical reactions at solid electrodes is described. This technique gave reproducible concentration gradients at the electrode surface by intermittently stirring the electrolyte in the vicinity of the electrode by means of electronically pulsed gas bubbles. Under the proper conditions current-voltage curves could be recorded automatically with a polarograph and interpreted in a manner similar to polarograms. The method has been found to be controlled by semi-infinite linear diffusion. Analytical applications and studies of catalyzed electrochemical reactions involving oxygen are discussed. ) unless CC License in place (see abstract). ecsdl.org/site/terms_use address.
