PURPOSE:To make it possible to suppress any increase of gas-pressure in the battery in the caption by on enclosing a gaseous phase reaction-catalyst coated with a specific membrane in an enclosed type storage battery such as a nickel- cadmium storage battery, a nickel-hydrogen storage battery or a lead storage battery, etc. CONSTITUTION:A gaseous phase reaction-catalyst 1 including gas permeable micro-pores whose average pore diameter is less than 1mum, and coated with a water repellent and alkaline resistant membrane 2 is enclosed in a battery. Accordingly, leakage of electrolyte is prevented by and coating of the catalyst 1, gas consumption ability of the catalyst 1 does not decrease and increase of gas-pressure in the battery is surely suppressed. |
