摘要： PROBLEM TO BE SOLVED: To provide a working gas circulation type hydrogen engine operated at high heat efficiency by removing hydrogen and oxygen from circulating gas delivered from a combustion chamber and resupplied into the combustion chamber via a circulation passage section.
SOLUTION: In this hydrogen engine, hydrogen, oxygen, and argon gas as working gas, are supplied into the combustion chamber 21 to thereby diffuse and burn hydrogen. Hydrogen and oxygen contained in circulation gas delivered from the combustion chamber 21 are converted into water (steam) by an oxidation catalyst 65. A condensation section 66 condenses steam in gas led to flow into the condensation section 66, and steam is separated and removed from gas. Thereby, since the amount of hydrogen and oxygen in circulation gas is reduced, a ratio of specific heat κ of working gas is not decreased. As a result, the hydrogen engine is operated at high efficiency.
