摘要： A single fuel cell includes: a power generation part where an anode, an electrolyte, and a cathode are stacked; a non-power generation part that does not include the power generation part; and a gas seal film for at least partially covering a surface of the non-power generation part. The gas seal film includes a first layer and a second layer laminated to each other. The first layer has lower electronic conductivity than the second layer, and the second layer has lower oxygen ion conductivity than the first layer.
