| 摘要 |
A hydrogen generator that can be operated in a broad temperature range is disclosed, which comprises a first ammonia conversion part having a hydrogen-generating material which reacts with ammonia in a first temperature range so as to generate hydrogen; a second ammonia conversion part having an ammonia-decomposing catalyst which decomposes ammonia into hydrogen and nitrogen in a second temperature range; an ammonia supply part which supplies ammonia; and an ammonia supply passage which supplies ammonia from said ammonia supply part to the first and second ammonia conversion parts. The first temperature range includes temperatures lower than the second temperature range, and hydrogen is generated from ammonia by selectively using the first and second ammonia conversion parts. An ammonia-burning internal combustion engine and a fuel cell having the hydrogen generator are also disclosed. |
