Abstract

Two limiting equations for the flow of mass or heat to or from the electrode in the region of hydrogen evolution were derived. The equations are valid for aqueous solutions saturated with hydrogen at low values of the Reynolds number.

    Citation Excerpt :

    Ibl considered convectionless diffusion during the waiting time between departure and growth of the subsequent bubble [12] and succeeded in establishing a first mass transfer correlation for gas-evolving electrodes [13]. His model was later modified by Roušar and Cezner [14]. In another attempt, convective mass transfer induced by bubble growth was regarded as the controlling mechanism [15,16].

    Citation Excerpt :

    Eucken [14] found that very high rates of the current density are necessary causing to disappear the discrepancy between the total rate of generated substance and the rate of substance transferred into the gaseous phase. In contrast, Roušar and Cezner [15] concluded from evaluation of bubble growth data that current densities above 10 A m−2 are sufficient to consider the fraction remaining in solution negligible. Kadija et al. [16–18] observed that the transferred fraction was the smaller the larger the solution flow velocity past the electrode was.
