The invention relates to an improvement in a cell which is normally susceptible to damage from overcharging comprised of a negative electrode, a positive electrode, and an electrolyte comprised of an overcharge protection salt carried in a carrier or solvent. Representative overcharge protection salts are embraced by the formula:MQwhere M is an electrochemically stable cation selected from the group consisting of alkali metal, alkaline earth metal, tetraalkylammonium, or imidazolium groups, and Q is a borate or heteroborate cluster and a is the integer 1 or 2.

The invention relates to the electrolysis of aqueous electrolyte solutions containing GeO; hydroxide and water with metal alloy electrodes, such as, copper or tin rich alloy electrodes with alloying elements such as Sn, Pb, Zn, Cu etc, to generate Germane (GeH). Cu-rich alloy electrodes have been demonstrated to increase the GeHcurrent efficiency by almost 20% compared to Cu metal electrodes. Germanium deposition has been found to be either absent or minimal by using Cu-rich alloy electrodes. Several different methods for maintaining the cell performance or restoring the cell performance after a reduction in current efficiency over time, have been identified. A titration-based method for the analysis of the electrolyte, to obtain the concentration of GeOand the concentration of hydroxide has also been disclosed.

A method for generating hydrogen in a production facility having a catalytic steam reformer, a boiler downstream of the catalytic steam reformer, optionally having a prereformer, and optionally having a shift reactor, wherein the reformer feed gas mixture is formed using a steam-containing recycle gas mixture which was formed from boiler effluent. The boiler generates steam which may be used to form the reformer feed gas mixture, used elsewhere in the production facility, and/or used for export steam.

The disclosure relates to new compositions comprising an, BFHanion that may be prepared chemically or electrochemically by oxidation of BFHsalts. This anion can be generated electrochemically in a voltammetry experiment, or by chemically by treatment of the (2−) anions with powerful oxidants such as XeF2 or NO2(+) salts. The new compositions can be used as 1 electron chemical oxidants and in electrochemical cells such as lithium ion batteries where their fomation at elevated potential can serve to limit the upper limit of voltage during the overcharge of such a cell.
