摘要:
In a gas fuel cell there are provided bipolar low-pressure electrodes each formed of a flexible graphite foam foil carrying active electrode layers on opposite faces. The gas-side face of each active electrode layer is provided with raised portions which, together with the adjoining foil face, define a channel system forming a closed gas chamber. The raised portions are so arranged that the gas which enters and leaves the gas chamber through an inlet opening and an outlet opening provided in the active electrode layer is substantially evenly distributed over the entire area of the gas-side face of the active electrode layer.
摘要:
A galvanic cell is described which is capable of implantation in living tissue. The cell is essentially a metal/oxygen cell and is covered with or encapsulated in a layer of material in the form of an oxygen permeable membrane, the anode and cathode components being separated by a barrier which is relatively impermeable to oxygen and not permeable to larger molecules, such as oxides of the metal, while allowing hydroxyl ions to diffuse through it.

A method for protecting the asbestos fiber matrix of a hydrogen oxygen type fuel cell from the degradative effects induced by a potassium hydroxide fuel cell electrolyte which comprise adding potassium silicate in proper proportions to the potassium hydroxide electrolyte.
摘要:
In an air cell comprising an outer metal casing constituting an anode terminal of the cell, and an anode inner casing containing anode active mass therein, there is provided an alkaline resistance insulative thin film covering over the outer vertical side surface of the anode casing, and a conductive metal penetrating through the vertical center portion of the insulative thin film to electrically and liquid-tightly connect the anode inner casing with the outer metal casing.
摘要:
A process for the complete recovery of possible electrolyte leaks of a fuel cell fed with oxidizing and reducing gases comprising separately recovering the leaks from the respective circuits of said two gases, collecting said leaks while preventing any mixture of said gases and recycling to the cell the whole of said collected electrolyte leaks.
摘要:
Method of producing a compact, storable structural member, formed of electrodes, cover layers and a support frame, for fuel elements includes welding a first metal screen to one side of a framework formed of plastic material, placing a support frame of at least one screen of plastic material adjacent the first metal screen, welding a second metal screen to the other side of the framework so as to sandwich the support frame between the first and second metal screens, spraying on the metal screens at least one layer of fine-granular ion exchanger material suspended in a dissolved binding agent, and thereafter applying to the ion exchanger layers at least one layer of a catalyst suspended in a dissolved binding agent; and structural member produced by the method.
摘要:
Storable air depolarization cell provided with an electrolyterepellent porous positive electrode, a separator layer and a powdered negative zinc electrode. Spaces having walls that are permeable to gases and impervious to the electrolyte extend along the negative electrode and serve as gas collectors and communicate through valve means with an exhaust space in the upper part of the cell. Such a cell can be stored for a long time prior to use and is leakproof as to electrolyte.

A RECHARAGEABLE ZINC CELL AND BATTERY, PREFERABLY A ZINCAIR CELL AND BATTERY, ARE DISCLOSED IN WHICH THE CELL COMPRISES (1) A CIRCULAR CASING HAVING A CIRCULAR RESERVOIR WITH ELECTROLYTE CONTAINED THEREIN; (2) A ROTATABLE ELECTRODE, HAVING AT LEAST ONE PLANAR ZINC SURFACE, ENCLOSED COAXIALLY IN THE RESERVOIR; (3) A STATIONARY PLANAR COUNTERELECTRODE SPACED FROM THE ROTATABLE ELECTRODE; (4) MEANS
FOR PREVENTING THE ELECTROCHEMICAL REACTION IN THE AXIAL AREA OF THE ZINC SURFACE; (5) WIPER MEANS DISPOSED BETWEEN THE ELECTRODES FOR LIGHTLY ABRADING THE ZINC SURFACE, AND (6) MEANS FOR AGITATING THE ELECTROLYTE TO MAINTAIN PARTICULATE MATTER IN SUSPENSION.
摘要:
Process for activating a hydrogen electrode in a fuel cell during or prior to the operation of the cell by supplying hydrogen to both electrodes for a specified limited time, establishing certain electrically conductive conditions for a specified time, and discontinuing the hydrogen supply to the oxygen electrode. The cell then resumes its optimum operating capacity.
摘要:
A TWO-ELECTRODE RECHARGEABLE METAL/AIR OR METAL/OXY GEN DEPOLARIZED ELECTROCHEMICAL CELL AND METHOD OF GENERATING ELECRICITY THEREFROM ARE DESCRIBED. THE ELECTROCHEMICAL CELL COMPRISES AN ANODE CAPABLE OF BEING REGENERATED, A COMPOSITE CATHODE HAVING AN OXYGEN PERMEABLE HYDROPHOBIC MEMBER LAYERED WITH CATALYST, AND A CURRENT COLLECTOR IN CONTACT WITH THE LAYERED CATALYST ON SAID MEMBER. THE CATHODE IS CONSTRUCTED AND ARRANGED IN ORDER THAT THE CURRENT COLLECTOR IS IN REMOVABLE ELECTRICAL CONTACT WITH THE CATALYST. THUS, FOR CELL DISCHARGE, THE CURRENT COLLECTOR CONTACTS THE CATALYST AND TRANSPORTS ELECTRONS TO THE EXTERNAL CIRCUIT. FOR CELL RECHARGE, THE CURRENT COLLECTOR IS ELECTRICALLY SEPARATED FROM THE CATALYST WHEREBY NUMEROUS DISCHARGE-RECHARGE CYCLES OF THE CELL MAY BE EFFECTED WITHOUT DAMAGE TO THE CATHODE.
