PROBLEM TO BE SOLVED: To enhance the response of an evaporator, while reducing the size thereof, by heating third and fourth fluids up to an appropriate temperature to be lower than the temperature of a second fluid, without having to increase heat exchangers in the fuel cell as a whole. SOLUTION: A plurality of first metal plates 17, 17 and a plurality of second metal plates 18, 18, having first and second channels 23 and 24 passing first and second fluid, respectively, on the inside are laid alternately in layers, with first partition plate being interposed between the adjoining first metal plate 17 and the second metal plate, thus constituting a first section 27. On one side of two first metal plates 17, 17 located at the opposite ends of the first section 27, third and fourth metal plates 19 and 20, having third and fourth channels 25 and 26 passing third and fourth fluids on the inside, are laid in layers via second and third baffle plates 22 and 30. |
