The present invention relates to a fuel cell device using a liquid fuel, improves recovery of moisture contained in the exhaust air discharged from the fuel cell, and simplifies structure of generated water recovery. The fuel cell device is a fuel cell device 2 using the liquid fuel (diluted fuel M), and includes a water separation part 16 capable of separating water from exhaust air generated in the fuel cell 4 , to which the fuel m as well as an air Ar are supplied, by letting the exhaust air pass through and by causing pressure changes in the exhaust airflow. The water separation part is constructed in such a manner that it includes a narrow portion formed in channels where the exhaust air passes through for causing pressure changes in the exhaust air passing thereat.
