Abstract

A method of measuring a quantity of moisture in an electrode includes at least three steps as follows: disposing an electrode, which is a measurement target sample, inside a container provided with a gas introduction pipe and a gas discharge pipe; heating the electrode by supplying inert gas heated to a predetermined temperature in advance to the inside of the container through the gas introduction pipe, and vaporizing moisture adsorbed to the electrode; and collecting the moisture vaporized from the electrode, together with the inert gas through the gas discharge pipe and determining the quantity of the collected moisture. In addition, a moisture quantity measuring apparatus includes a container that has a gas introduction pipe and a gas discharge pipe, a heating unit, and a moisture quantity measuring unit that collects moisture vaporized from a sample, through the gas discharge pipe and determines the quantity of collected moisture.
