Title:
Fuel cell device
Document Type and Number:
Japanese Patent JP6277898
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a fuel cell device in which, while compactness of a device is achieved by enabling a water evaporator to be arranged close to a reformer, heat transfer from the reformer to the water evaporator is sufficiently suppressed, thereby to achieve a prompt temperature rise in a cell stack.SOLUTION: In a fuel cell device FC, a water evaporator 206 and a reformer 208 are housed at the inside of a unit casing 205, and a combustion gas exhaust passage 502 is configured such that combustion gas flows while applying heat to the reformer 208, air flowing through an air heating passage 301 and the water evaporator 206 in order. The fuel cell device FC further includes a steam passage 207 which is arranged in a space formed between the water evaporator 206 and the reformer 208, and flows steam from the water evaporator 206 to the reformer 208.SELECTED DRAWING: Figure 3
