摘要： The invention concerns a device for catalytic recombination of gases for alkaline batteries with shortened zinc anode. The invention concerns a device for catalytic recombination of gases formed when charging a zinc anode alkaline battery, characterized in that it consists of a catalytic mass in contact with a crosslinked cellular metal foam serving as catalyst support and heat dissipating structure, said catalytic mass consisting of a mixture of carbon black including metal of platinum metals, and of a hydrophobic binder, the whole assembly being heat-treated to cause the hydrophobic binder of said catalytic mass to be sintered. Said device is advantageously connected to one of the terminals of the battery or to any other metal part constituting part of the cover of the battery case, so as to promote discharge of the calories produced. Such a device enables, in a long lasting manner during the charge-discharge cycles, limited internal pressure levels to be maintained, in particular in installations designed to operate without maintenance.
