Hydrogen gas supply system for hydrogen engine and method of supplying hydrogen gas to the hydrogen gas supply system.

摘要

A hydrogen gas supply system for a hydrogen engine has a hydrogen gas cartridge (11) which is detachably attached to the engine. The cartridge has a casing (13) in which hydrogen gas storage alloy (x) and a heating medium passage (15) for heating the hydrogen gas storage alloy are housed. The engine is provided with a hydrogen gas supply passage which leads hydrogen gas discharged from the hydrogen gas cartridge (11) to the engine, a heating medium supply passage which supplies heating medium to the heating medium passage (15) in the hydrogen gas cartridge (11) and a heating medium return passage through which the heating medium flows out of the hydrogen gas cartridge (11) is returned. The hydrogen gas cartridge (11) is provided with a hydrogen gas takeout port, a heating medium inlet and a heating medium outlet. The hydrogen gas takeout port, the heating medium inlet and the heating medium outlet are respectively connected to and disconnected from the hydrogen gas supply passage, the heating medium supply passage and the heating medium return passage in response to attachment and detachment of the hydrogen gas cartridge.
