    摘要： A power generation system utilizing an electrochemical cell comprising a reactive metal anode, a cathode spaced from the anode and an electrolyte comprising an aqueous solution of the hydroxide of the reactive metal is disclosed. The hydroxide concentration in the electrolyte is controlled by contacting the electrolyte with an acid anhydride to form an insoluble compound of the reactive metal. The insoluble compound is separated from the electrolyte and the electrolyte is recirculated to the electrochemical cell.

    摘要： Gas diffusion electrodes, gas generating or consuming electrochemical cells utilizing such electrodes, and a method of preparing such electrodes are disclosed. The electrode comprises an electronically conductive porous body defining respective gas and electrolyte contacting surfaces. The electrode is prepared by forming the porous body, disposing the electrolyte contacting surface in contact with an electrolyte, and contacting the gas contacting surface with a gaseous atmosphere. Current is passed through the porous body at a degree of electrode polarization much higher than normal whereby modification of the electrode material is effected. If desired, a catalyst may be incorporated in the electrode and is subjected to pretreatment as well. The inventive electrodes exhibit superior voltage performance under oxygen polarization conditions.

    摘要： A power generation system utilizing an electrochemical cell comprising a reactive metal anode, a cathode spaced from the anode and an electrolyte comprising an aqueous solution of the hydroxide of the reactive metal is disclosed. The hydroxide concentration in the electrolyte is controlled by contacting the electrolyte with acids or salts thereof having a first anion comprising at least two elements with at least one of the elements being a non-metal. Upon contact with the electrolyte, the anion hydrolyzes to yield at least second or third anions which react with the hydroxide of the reactive metal to yield compounds thereof which are insoluble in the electrolyte. The insoluble compounds are separated from the electrolyte and the electrolyte is recirculated to the electrochemical cell.
