1. A method for activating a gas, comprising
electrically contacting an electrically conductive aeromaterial having a pore space comprising the gas, the electrically conductive aeromaterial having a porosity of more than 99%, and
flowing at least one electric current, which varies over time, through the electrically conductive aeromaterial,
wherein the electrically conductive aeromaterial exhales gas from the pore space when an electric power consumption is increased and inhales gas from the surroundings of the electrically conductive aeromaterial when the power consumption is decreased,
wherein
a time-varying pulsed current having predetermined pulse power levels, pulse durations and pulse spacings is fed through the aeromaterial
the temperature of the electrically conductive aeromaterial is changed by the time-varying current by 100° C. or more within one second or less, and
the pulse intervals are set up at least one order of magnitude greater than the pulse durations.
