According to the present invention, energy held by fuel such as city gas is converted into electric power by a fuel cell,
Used effectively. A fuel cell includes a reformer, in which carbon hydrogen in fuel, for example, methane in city gas, is converted to carbon dioxide and hydrogen by steam. Hydrogen reacts with oxygen in the air to form water, which generates electric power. On the other hand, carbon dioxide is extracted from the fuel cell and introduced into a plant growing room such as a lettuce. As a result, energy held by fuel such as city gas is effectively converted into electric power, and carbon dioxide can be supplied to the plant growing room. Further, since carbon dioxide can be reduced by cultivated plants, it can contribute to prevention of global warming. Energy is thus circulated.

At 0 ° C., carbon monoxide is reacted with steam to convert the remaining carbon monoxide to carbon dioxide. CO + H 2 O → CO 2 + H 2 A gas (CO 2 + H 2 ) containing almost no carbon monoxide and dust-free air supplied from the reformer 4 are introduced into the battery body 3, and the gas in the gas is introduced. Hydrogen reacts with oxygen in the air. 2H 2 + O 2 → 2H 2 O + E The energy (E) generated at this time is converted into electric power and taken out.
