Electrical power producing device

Abstract

A device includes a heat exchanger connected to an air line through which air flows and to a hydrogen line through which liquid-state hydrogen flows. The heat exchanger is configured to produce liquid-state air as the air and the liquid-state hydrogen exchange heat with each other. The device also includes a carbon dioxide separator connected to the heat exchanger via the air line and the hydrogen line. The carbon dioxide separator is configured to separate at least a portion of carbon dioxide from the air. The device also includes an air storage container connected to the heat exchanger via the air line. The air storage container is configured to store the liquid-state air discharged from the heat exchanger. The carbon dioxide separator is configured such that the air and the hydrogen exchange heat with each other inside the carbon dioxide separator.
