Equilibrium behavior for the H+/H2 couple has been verified at gold electrodes from partial pressures of 1 to about 6 × 10−4 atm. The study was conducted in a high-purity, tight, electrochemical system in which the Po2 above the cell solution was

The io for the H+/H exchange on Pt was found to be dependent on H2SO4 concentration, giving a linear log—log relation with a slope of 0·5. For any given H2SO4 concentration, io was virtually independent of potential to an anodic value at which the

Open circuit dependence of potential on oxygen partial pressure as well as potentiostatic behavior in O 2 - and He-saturated solution were determined. Stable hydrogen-oxygen species were formed, but potential-determining reversbility was found only i

Alloys of Al with 1.2, 5.2 or 9.5% by weight Zn were discharged in simulated seawater at 19–25°C. Current densities of 25.5 to 0.63 mA cm −2 gave discharges lasting from about 13 h to 28 days. Production of electrical current during discharge ac

The thermal conductivities for binary and ternary mixtures of H/sub 2/, D/sub 2/, and HD were determined experimentally and by calculation. Expressions which involve only the thermal conductivities of the components and their concentrations were deve

H 2 reactivity with steady-state formed Pt—O is far slower and more complex than H 2 reactivity with transient formed Pt—O ad . Under steady state, dermasorbed oxygen, adsorbed sulphate ions, and the uncertainty in the types and total quantities

Summary By lowering the concentration of a reactant or product (or both) of an equilibrium exchange, the effect of impurities on io can be detected when the concentration of these impurities are significant in relation to the equilibrium potential of

The character of platinum-bead and -(111) electrodes at anodic steady-state potentials was determined by analysing with cathodic galvanostatic pulses for reducible, Pt-associated species. There was a considerable amount of potential overlap in the re

Hydrogen formed by cathodic polarization of a bright platinum electrode in CO-saturated 1 M H 2 SO 4 is shown to remain associated with the electrode for relatively long periods of time. Such hydrogen causes unusual open-circuit potential behaviour a
