Abstract
A tubular fuel cell comprises a cylindrical internal electrode having electrical conductivity, a lamination of a first catalytic layer, an electrolytic layer, and a second catalytic layer laminated in that order on an outer circumferential surface of the internal electrode, and an electrically conductive exterior coil wound around an outer circumferential surface of the second catalytic layer. The tubular fuel cell further comprises an electrically conductive spacer which has an outside diameter greater than that of the exterior coil.
