Abstract
Experiments on the emergence of a counterflow in gas-generating cells with high continuous electrodes and a small electrode–membrane gap, in which the bubble layer abruptly extends over the entire cross-section of the cell, may be explained in terms of a “two-speed” model of interacting jets of the bubble layer and the free liquid developed earlier. The viscous-flow model provides only a qualitative description of the phenomenon. The difference in the magnitude of the electrode screening with gas and the gas content near the surface as parameters of macroscopic models of electrolyzers is stressed. The role played by the electrolyte oversaturation with gas in the bubble layer formation dynamics is analyzed. The relative coefficient of hydraulic loss in the initial part of the flow is estimated.
