| 20090047422 | Method for Manufacturing Tube-Type Fuel Cell - The present invention mainly intends to provide a method for manufacturing a tube-type fuel cell by which a tube-type fuel cell with good adhesion can be produced without blocking gas flow channel in its inner current collector. In order to achieve the object, the present invention provides a method for manufacturing a tube-type fuel cell, comprising: a filling step of providing a columnar-shaped inner current collector having a gas flow channel on its outer peripheral face and filling the gas flow channel with a removable substance to form a removable portion; a functional layer forming step of forming a functional layer on at least the removable portion; and a removing step of removing the removable portion after the functional layer forming step. | 02-19-2009 |
| 20090148741 | Fuel Cell - a fuel cell capable of improving heat exchange efficiency with respect to tubular fuel cells is provided. A fuel cell includes a hollow electrolyte membrane, hollow electrodes arranged on an inside and an outside of the electrolyte membrane, respectively, and an internal charge collector arranged inside of the electrolyte membrane and the electrodes, wherein the internal charge collector is hollow and made of a nonporous member. | 06-11-2009 |
| 20090155659 | Tubular Fuel Cell - A tubular fuel cell includes an inner current collector, a membrane-electrode assembly, and seal portions provided at the axial end portions of the membrane-electrode assembly, respectively. The membrane-electrode assembly includes an inner catalyst layer provided on the inner current collector, an electrolyte membrane provided on the inner catalyst layer, and an outer catalyst layer provided on the electrolyte membrane. The axial length of the outer catalyst layer is shorter than the axial lengths of the electrolyte membrane and the outer catalyst layer. The axial end face of the outer catalyst layer and the axial end face of the inner catalyst layer are located on the opposite sides of the seal portion in each side of the tubular fuel cell. | 06-18-2009 |
| 20090162714 | Tubular Fuel Cell Module and Manufacturing Method Thereof - A tubular fuel cell module is provided with a tubular cell of a tubular fuel cell, and a heat transfer pipe through which a heating/cooling medium flows to selectively heat and cool the tubular fuel cell. The heat transfer pipe includes a first straight portion, a second straight portion, and a bent portion that connects the first straight portion with the second straight portion. At least a portion of the tubular cell is arranged on at least one of the first straight portion and the second straight portion. As a result, the reliability of a seal of the tubular fuel cell module is improved. | 06-25-2009 |
| 20090253009 | Fuel cell - The present invention provides a fuel cell which is capable to improve heat exchange efficiency with a plurality of tubular cells. The fuel cell of the present invention comprises: a plurality of tubular cells; heat exchangers arranged at the outside of the tubular cells, wherein at least a part of the outer circumferential surface of said tubular cells and the peripheral surface of said heat exchangers have face contact with each other. | 10-08-2009 |
| 20090286130 | Water Repellent Layer-Forming Tape - The present invention mainly intends to provide a water-repellent layer-forming tape, which enables a water-repellent layer to be provided by a simple method. In order to achieve the object, the present invention provides a water-repellent layer-forming tape to be used for forming a water-repellent layer of a tube-type fuel cell, comprising a plurality of fibrous shape-retaining materials and a water-repellent portion formed to connect the plurality of fibrous shape-retaining materials, wherein the water-repellent portion contains a water-repellent material and an electro-conductive material. | 11-19-2009 |
