<p>A hydrogen engine 10 supplies hydrogen, oxygen, and an argon gas serving as a working to a combustion chamber 21 to combust the hydrogen. H2O in a recirculating gas discharged from the combustion chamber 21 is separated and eliminated from the gas by a condenser 66. A three-way valve 72 is switched over in such a manner that the recirculating gas flows through a product eliminating section 70 (a carbon dioxide absorbing unit 71), when the concentration of carbon dioxide in the recirculating gas is higher than a predetermined concentration, so that the carbon dioxide is separated and eliminated from the recirculating gas.</p> |
