| Summary: | This invention relates to a heat exchanger applied to a vaporizer of a fuel cell system for example.
A plurality of water passages allowing flow of water, a plurality of alcohol passages allowing flow of alcohol and a plurality of high temperature gas passages heating the water passages and the alcohol passages are independently provided in a heat exchanging portion. Liquid alcohol is supplied from a first header to the alcohol passage and water is supplied from a second header to the water passage. The water passage is preferably adapted to make contact with a high temperature section of the high temperature gas passage and the alcohol passage is preferably adapted to make contact with the low temperature section of the high temperature gas passage. By separately vaporizing water and alcohol in this way, the mixing ratio of the water vapor and alcohol vapor can be controlled with high response. |
