Abstract: A cell module for a fuel cell according to embodiments of the invention includes a hollow-core electrolyte membrane; two electrodes one of which is arranged on the inner face of the hollow-core electrolyte membrane and the other of which is arranged on the outer face of the hollow-core electrolyte membrane; and first collecting members that are connected to the respective two electrodes. At least one of the two electrodes includes nano-columnar bodies on which electrode catalysts are supported. The nano-columnar bodies are formed on at least one of the first collecting members corresponding to the at least one of the electrodes that includes the nano-columnar bodies. At least part of the nano-columnar bodies are oriented toward the hollow-core electrolyte membrane.

Abstract: A membrane electrode assembly (11) for a tube-shaped fuel cell, which is provided with a tube-shaped solid electrolyte membrane (1); an outside catalyst electrode layer (2) formed on an outer peripheral surface of the solid electrolyte membrane (1); an inside catalyst electrode layer (3) formed on an inner peripheral surface of the solid electrolyte membrane (1); an outside collector (4) arranged on an outer peripheral surface of the outside catalyst electrode layer (2); and an inside collector (5) arranged on an inner peripheral surface of the inside catalyst electrode layer (3), is characterized in that at least one of the outside collector (4) and the inside collector (5) is a coiled collector that includes a coiled conductor.

Abstract: A thermoplastic shaped resin article may include, for example, a shaped base material and a thermoplastic resin sheet. A discontinuous metal film may be disposed on one surface of the resin sheet. The base material may be adhered to the resin sheet so that the metal film faces the base material. As a result, shaped resin articles may be prepared that have a metallic appearance and transmit visible light.

Abstract: A decorative article including a base layer essentially consisting of a resin sheet and a decorative layer attached to the base layer and essentially consisting of a resin film and a metal thin film formed on a lower surface of the resin film. The metal thin film is formed in a microscopically discontinuous pattern.
