DIRECT PRODUCTION OF ELECTRICAL PULSES FROM GALVANIC CELLS I,

Abstract

An experimental method was found to study the oscillatory behavior of anodic half elements in combination with a simulated, electromotively active counter electrode. The half elements under investigation were methanol and formaldehyde at platinized platinum electrodes and room temperature in sulfuric acid electrolyte. Simultaneous current and voltage oscillations of various amplitudes and frequencies were observed. Various waveforms of the oscillations were found and classified in oscillation patterns. A reaction mechanism explaining the oscillatory behavior has been suggested. Based on the theory that at least two simultaneous reactions are necessary for a periodic reaction to occur, two possible reactions were identified. Experimental evidence in support of the suggested mechanism is presented. A correlation between electrode activity and time effects on the oscillatory behavior of the half elements was established. Influence of electrode pretreatment (hydrogen deposition) on the oscillations was also investigated. (Author)
