FIELD: electricity.
SUBSTANCE: invention is attributed to device for catalytic gas recombination (DCGR) in alkaline accumulator with short zinc anode. In this invention device for DCGR produced during charging alkaline accumulator with zinc anode features catalytic mass applied on porous cellular foamed metal acting as catalyst carrier and heat-dissipating structure. The specified catalytic mass contains carbon black that includes platinum-group metal and hydrophobic binder which combination is heat-treated to provide hydrophobic binder agglomeration in specified catalytic mass. The said device is preferably connected with one of accumulator terminals or with some metal component that is part of accumulator casing cover to allow for produced heat dissipation.
EFFECT: maintaining limited pressure in charging and discharging cycles for a long period of time, especially in structures supposing lack of technical service.
