To provide a water evaporator which can suppress concentration unevenness of a reforming raw material in a gas mixture.SOLUTION: A water evaporator 50 has a container 51 disposed upstream a reformer in a fuel cell system. In the water evaporator 50, a reforming raw material and water are supplied into the container 51 so that the water heated by a heating part 60 provided on the lower side of the container 51 becomes water vapor. At the same time, the water vapor and the reforming raw material are mixed together so as to become a gas mixture which is led out into the reformer 33. The container 51 is provided with: a raw material introduction part 52 which leads the reforming raw material into the container 51; and a water introduction part 53 which leads the water into the container 51. Inside the container 51, there is provided a guide part 55 which guides, to the heating part 60, the reforming raw material thus led inside from the raw material introduction part 52.SELECTED DRAWING: Figure 2 【課題】混合ガスにおける改質用原料の濃度の偏りを抑制可能な水蒸発器を提供する。【解決手段】水蒸発器５０は、燃料電池システムの改質器の上流に配置される容器５１を備える。水蒸発器５０は、容器５１の内側に改質用原料と水とが供給され、容器５１の下部に設けられた加熱部６０によって水が加熱されて水蒸気になるとともに水蒸気と改質用原料とが混合して混合ガスとなり、混合ガスが改質器３３へ導出される。容器５１には、改質用原料を容器５１の内側に導入する原料導入部５２と、水を容器５１の内側に導入する水導入部５３と、が設けられている。そして、容器５１の内側には、原料導入部５２から導入された改質用原料を加熱部６０に向けて案内する案内部５５が設けられている。【選択図】図２
