  "textContent": "A hydrogen gas cooling method comprises: a preparation step of preparing a heat exchanger that comprises a layered body wherein a first layer in which a plurality of first channels that are micro channels are arranged, and a second layer in which a plurality of second channels that are micro channels are arranged, are layered; and a cooling step of cooling hydrogen gas by exchanging heat between the hydrogen gas flowing in the first channel with brine flowing in the second channel. In the cooling step, the hydrogen gas is made to flow in the first channel so that the hydrogen gas flowing in the first channel moves from one side to the other side in a specified direction that is perpendicular to the direction of layering of the first layer and the second layer, and the brine is made to flow in the second channel so that the brine flowing in the second channel moves from the other side to the one side in the specified direction. The temperature and flow rate of the brine introduced into the second channel is controlled so that the temperature of the brine at the outlet of the second channel is higher than the temperature of the hydrogen gas at the outlet of the first channel.",
