PURPOSE:To continuously generate fixed gas over a long time by bringing a liq. substance into contact with a solid substance through a translucent film to react them when the fixed gas is generated. CONSTITUTION:When the fixed gas (e.g. oxygen) is generated by bringing the solid substance (e.g. mangan dioxide) into contact with the liq. substance (e.g. aq. hydrogen peroxide) and reacting them, the liq. substance above-mentioned is brought into contact with the solid substance above-mentioned through the translucent film (e.g. polyvinyl alcohol film). As a result, the desired gas can be continuously generated over a long time. |
