US Patent:

43248454, Apr 13, 1982

Filed:

Jun 30, 1980

Appl. No.:

6/164382

Inventors:

Joseph F. Stockel - Rockville MD

Assignee:

Communications Satellite Corp. - Washington DC

International Classification:

H01M 1050

US Classification:

429101

Abstract:

A rechargable metal oxide-hydrogen cell having an electrode stack within a pressure vessel. The electrode stack is aligned on a control alignment member and has separate positive and negative bars coupling respective positive and negative electrodes to like terminals. A variable conductance heat pipe includes a portion of the alignment member and couples the interior of the electrode stack to a radiator. The heat pipe uses a working fluid such as Freon 21.

Communications Satellite Corporation - Washington DC

International Classification:

H01M 400

US Classification:

429 29

Abstract:

A sealed electric fuel cell of the type utilizing a reoxidizable compound as the positive electrode and a hexagonal nickel-rare earth metal hydride as the negative electrode is disclosed. The energy released by the electrochemical oxidation-reduction reaction of the anode appears in the cell as electrical energy.

International Classification:

H01M 1206

US Classification:

429 72

Abstract:

A rechargeable metal oxide-hydrogen battery which operates on the back-to-back electrode placement theory as opposed to single metal oxide-hydrogen couple cells is disclosed. Interconnecting of electrodes in series and construction of an electrode stack of series connected electrodes is utilized in one embodiment in place of bipolar construction to achieve high voltage operation. In a second embodiment, back-to-back construction is used for positive electrodes in a parallel arrangement of electrode connection to complete an operative cell. Individual cells are separated by a nonporous polymer separator which avoids the formation of electrolyte films which tend to electrochemically short each cell, yet are fashioned of light weight and volume to keep sizes to minimum dimensions. Interconnection of various cells is by means of bus bars coupled to electrode tabs. The entire stack of cells is held under compression by end plates and one or more tie rods, or, in the case of prismatic cell design, the stack can be held under compression by the walls of the battery container.
