Abstract: A rechargeable, electrical power storage system employing an electrical power storage medium in the form of a slurry containing active metal particles and an electrolyte solution, which system includes one or more metal-air cells, each including outer electrode apparatus including air electrode apparatus and being configured to define a liquid permeable housing; a volume of the active metal particles arranged within the housing so as to define a static bed which is saturated with the electrolyte solution; inner electrode apparatus arranged within the housing so as to be surrounded by the static bed. The system also includes apparatus for circulating an electrolyte solution through the static bed so as to dissolve discharge products that form therein as the slurry becomes electrically discharged, and apparatus for removing the dissolved discharge products from the circulating electrolyte. The electrical power storage system may be used for powering an electric vehicle.

Abstract: The invention provides an electrode for use in a primary metal/air battery or in a hydrogen-oxygen fuel cell comprising a current-collecting metallic structure and a metallic foamed or fiber mat having a first surface attached to a first surface of the structure, a second surface of the mat being impregnated with an inner hydrophobic waterproof barrier layer coated with an outer active catalytic layer.

Abstract: The invention provides an air cathode in combination with an oxygen-rich electrolyte-immiscible organic fluid for supplying oxygen thereto, as well as providing metal/air batteries and hydrogen-oxygen fuel cells incorporating the same.

Abstract: An electrical energy system including an electric utility having an electricity generating apparatus and distribution lines, a plurality of electric vehicles and electric power storage apparatus receiving electrical power from the electric utility and supplying electrical power to the plurality of electric vehicles and to the electric utility when required.
