NOVELTY - A tube-shaped fuel cell module (20) includes an external collector which collects power from fuel cells and has a corrugated plate structure in which convex and concave portions alternate repeatedly in one direction and which extends in an orthogonal direction. The external collector is made of material plated with gold, platinum, tantalum, or titanium; carbon-coated material; or titanium clad material coated with titanium. The module includes cell collector unit(s) (10) having the external collector and the fuel cells contacting concave surface along the entire lengths of the cells.    USE - As tube-shaped fuel cell module.    ADVANTAGE - The tube-shaped fuel cell module has greater power collecting efficiency than a tube-shaped fuel cell module in which only the end portions of the fuel cells contact the external collector. Because external collector has a corrugated plate structure, the collector expands at this time in a direction orthogonal to the stacking direction, similar to a spring. In this way, the external collector flexibly deforms, enabling uniform pressure to be applied to each fuel cell and improving collecting efficiency. When manufacturing the fuel cell module, the fuel cells can be easily positioned if the external collector already has a corrugated plate structure.    DETAILED DESCRIPTION - A tube-shaped fuel cell module includes tube-shaped fuel cells each having, in order from the inside, an internal collector, an inside catalyst electrode layer, a solid electrolyte membrane and an outside catalyst electrode layer; and an external collector which collects power from the fuel cells. The external collector has a corrugated plate structure in which convex and concave portions alternate repeatedly in one direction and which extends in an orthogonal direction. The module includes cell collector unit(s) having the external collector and the fuel cells contacting concave surface along the entire lengths of the cells. An INDEPENDENT CLAIM is included for a manufacturing method of a tube-shaped fuel cell module.    DESCRIPTION OF DRAWING(S) - The figure shows a perspective view of a tube-shaped fuel cell module.
