ABSTRACT:
In order to provide a gas generation apparatus such as a hydrogen gas generation apparatus for a fuel cell or an oxygen gas generation apparatus used in medical sites and at the time of disasters in which a solid gas generating agent such as metal is brought into contact with a reaction liquid to generate hydrogen gas or oxygen gas, a gas generation apparatus A having a solid gas generating agent and a reaction liquid in which the solid gas generating agent and the reaction liquid are stored respectively in separate storing vessels21, 31and in which the reaction liquid is supplied into the gas generating agent-storing vessel to generate gas by capillary-active connection of the respective storing vessels assumes a constitution in which capillary-active connection is shut off when a pressure of the gas is raised. In the above gas generation apparatus, generation of the gas can automatically be controlled by a simple mechanism when the gas is not consumed, and therefore generation of excessive gas can be controlled.
