NOVELTY - A collector has a porous component (12b) which touches a membrane-electrode assembly, a plate-shaped separator (12a), and a rib which connects the plate-shaped separator with the porous component. An electrolyte layer (11a) is arranged in side of the membrane-electrode assembly clamped by a fuel electrode (11c) and an oxygen electrode (11b). A gas flow path for supplying fuel gas to the fuel electrode, and for supplying oxidation gas to the oxygen electrode is formed. The collector picks out generated electric current by reaction with fuel gas and oxidation gas.    USE - Collector is used for fuel cell (claimed) such as hydrogen fuel solid polymeric type fuel cell, direct methanol fuel cell, aqueous-alkali-solution type fuel cell, phosphoric acid fuel cell, molten carbonate type fuel cell and solid oxide fuel cell used for power supply for vehicle and household applications.    ADVANTAGE - The collector has light weight, low electrical resistance and thermal conductivity, and high corrosion resistance.    DETAILED DESCRIPTION - A collector has a porous component (12b) which touches a membrane-electrode assembly, a plate-shaped separator (12a), and a rib which connects the plate-shaped separator with the porous component. The rib contains carbon nanotube vertically oriented with respect to the porous component or the plate-shaped separator. An electrolyte layer (11a) is arranged in one or more sides of the membrane-electrode assembly clamped by a fuel electrode (11c) and an oxygen electrode (11b). A gas flow path for supplying fuel gas to the fuel electrode, and for supplying oxidation gas to the oxygen electrode is formed. The collector picks out generated electric current by reaction with fuel gas and oxidation gas. The plate-shaped separator separates gas supplied to the fuel electrode, and gas supply to the oxygen electrode. The rib further contains resin impregnated into a carbon nanotube. An INDEPENDENT CLAIM is included for manufacture of collector.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the stacked structure of the collector and the membrane-electrode assembly.
