PROBLEM TO BE SOLVED: To provide a fuel battery device in which long-term reliability is improved.SOLUTION: A fuel battery device according to the invention comprises: a fuel battery cell 19 configured to generate power using fuel gas and oxygen-containing gas; a reformer 3 that is able to cause a reform reaction with water vapor used to produce fuel gas supplied to the fuel battery cell 19; a water treatment device 9 configured to purify water to be supplied to the reformer 3; a water tank 11 configured to store water to be supplied to the reformer 3 after treated by the water treatment device 9; and a connection pipe 41 configured to connect the water treatment device 9 and water tank 11. The connection pipe 42 has an air bubble circulation accelerating part 42 by which air bubbles in water supplied by the water treatment device 9 is caused to flow to the water tank 11 or to outside. Accordingly, accumulation of air bubbles in the connection pipe 42 can be restricted and, therefore, the fuel battery device in which long-term reliability is improved can be provided. |
