Abstract: Buildup of unreacted hydrogen gas in sealed electrochemical cells has been prevented by inserting a hydrogen absorbing device into the cell before sealing. This hydrogen absorbing device is preferably a discrete shaped body, e.g., cylindrical or ring shaped, encased in an electrolyte impermeable, but hydrogen gas permeable membrane and includes a material which will react chemically with hydrogen gas, a catalyst for the hydrogen consuming reaction, and a compatible binder which maintains the reactant and catalyst in the form of a discrete shaped body which is porous to hydrogen gas.

Abstract: An alkaline silver oxide cell having a negative electrode, an alkaline electrolyte, a positive electrode comprising divalent silver oxide housed in a positive terminal cylindrical container having an upstanding wall and a closed end, and wherein an oxidizable metal strip, such as a zinc ring, is interposed between the positive electrode and the inner upstanding wall of the container so as to achieve a cell having a unipotential discharge level on low drain conditions.

Abstract: A hybrid battery is described. The battery comprises two different cells electrically connected in parallel, a first cell being an alkaline aluminum-air cell and the second cell being an alkaline zinc-manganese dioxide cell. The battery is particularly useful as a power source for electrically operated devices which require long periods of relatively low electrical current alternating with short periods of relatively high electrical current.
