Abstract:
1. An electrochemical reactor stack comprising a plurality of longitudinally stacked electrochemical reactor bundles having an electrochemical reactor bundle structure, comprising a plurality of tube fuel cells, in which each cell is formed of a dense ion conductor as electrolyte and cathode as air electrode which are laminated to an anode as fuel electrode material having a tube structure, the plurality of tube fuel cells are arranged in one-dimensional direction and are electrically connected in parallel or in series by collector wiring, wherein the tube structure comprises submillimeter diameter tubes having a tube diameter not greater than 2 mm and a tube thickness not greater than 0.5 mm, part of an anode tube is exposed at one end, with the electrolyte not laminated, to form an exposed anode part which functions as an external lead electrode thereof, the tubes are housed in a cathode porous collector element which functions as a collector, each tube cell is connected by coiling a thin metal wire of collector wiring around the exposed anode part and is connected to a collector sheet, the collector sheet is connected to the cathode porous collector element of another bundle to form a stack structure, and an upper surface and a portion of the porous collector element where the cells come out are covered by a seal layer of a seal member functioning as an electrical insulator and gas seal.
