ABSTRACT:
A fuel cell module that includes: a plurality of tubular fuel cells, each of which contains a cylindrically shaped inner electrode that exhibits conductivity, a first catalyst layer, an electrolyte layer, and a second catalyst layer laminated sequentially to the outer peripheral surface of the inner electrode, and an external coil that exhibits conductivity and is wound around the outer peripheral surface of the second catalyst layer in such a manner that a first coil section with a loose winding pitch is sandwiched between second coil sections with a tight winding pitch; and a current collecting member that exhibits conductivity and is provided with a plurality of openings into which the tubular fuel cells can be inserted, wherein the first coil sections and the openings fit together.
