“…Therefore, diffusion coefficients measured by the capillarity method are much higher than values obtained electrochemically, since the latter values include a migration component [41]. Figure 1.9 compares the results of Hsie and Selman taken from polarographic measurements to those obtained by other methods [42][43][44][45].…”

“…Although less accurate than our optical measurements and mainly at different compositions, his diaphragm cell results at 0.5M ZnC12-3.0M KC1-H20 do agree well with ours. Some earlier diffusion measurements by Loftus et al (12) of ZnC12 in 3.5M KCI using the capillary method were improperly analyzed because the systems were treated as binaries, even though their "Zn diffusivity" is approximately the same as our Du.…”

Mutual diffusion coefficients were measured at 298.15 K for aqueous mixtures of 0.5 normalmol‐dm−3 ZnCl2 with normalKCl at concentrations of 0.5, 1.25, 2.0, and 4.0 mol‐dm−3, using Rayleigh interferometry. These systems correspond to a fully charged zinc‐chlorine storage battery at various supporting electrolyte concentrations. The ZnCl2 main term diffusion coefficient is nearly independent of concentration, whereas the normalKCl main term varies by one‐third. The ZnCl2 cross term is small and positive. The normalKCl cross term varies from moderately large and positive to quite large and negative as the normalKCl concentration increases. The experimental values cannot be reliably approximated by Nernst‐Hartley type equations, even with speciation assumptions. Mutual diffusion data, together with transference number and conductivity data (when available), can be used to calculate ion transport in systems with combined electrical and diffusive transport.

The growing demand for renewable energy sources has accelerated a boom in research on new battery chemistries. Despite decades of development for various battery types, including lithium‐ion batteries, their suitability for grid‐scale energy storage applications remains imperfect. In recent years, rechargeable hydrogen gas batteries (HGBs), utilizing hydrogen catalytic electrode as anode, have attracted extensive academic and industrial attention. HGBs, facilitated by appropriate catalysts, demonstrate notable attributes such as high power density, high capacity, excellent low‐temperature performance, and ultralong cycle life. This review presents a comprehensive overview of four key aspects pertaining to HGBs: fundamentals, principles, materials, and applications. First, detailed insights are provided into hydrogen electrodes, encompassing electrochemical principles, hydrogen catalytic mechanisms, advancements in hydrogen catalytic materials, and structural considerations in hydrogen electrode design. Second, an examination and future prospects of cathode material compatibility, encompassing both current and potential materials, are summarized. Third, other components and engineering considerations of HGBs are elaborated, including cell stack design and pressure vessel design. Finally, a techno‐economic analysis and outlook offers an overview of the current status and future prospects of HGBs, indicating their orientation for further research and application advancements.
