It is to provide a tubular fuel cell which is formed in a tubular shape by a bending process and has an advantage of realizing a compact size of a cross section and further realizing a compact bulk, and a method of producing such a fuel cell. The tubular fuel cell (1) includes a tubular membrane electrode assembly (2) and a current collector (6) provided at the membrane electrode assembly (2) . The tubular membrane electrode assembly (2) includes an ion conductive membrane (3), a fuel side electrode (4) disposed on one side in a thickness direction of the ion conductive membrane (3), and an oxidizing agent side electrode (5) disposed on the other side in the thickness direction of the ion conductive membrane (3). In a cross section in a direction crossing a longitudinal direction of the tubular fuel cell (1), the membrane electrode assembly (2) has a shape bent in a folding direction. |
