Publication number: 20040091758Abstract: In a fuel cell assembly comprising at least one cell including an electrolyte layer, a pair of gas diffusion electrode layers interposing said electrolyte layer between them, and a pair of flow distribution plates (5) for defining passages (10, 11) for fuel and oxidizer gases that contact said gas diffusion electrode layers, a heater (62) and various sensors (61a, 61b and 61c) are formed at least one of the flow distribution plates so that the work needed for installing the heater and sensors is simplified. By embedding them in a substrate, the need for a complex sealing arrangement can be eliminated. In particular, if each flow distribution plate is formed by performing an etching process on a substrate, and forming the heater and sensors in succession to the step of forming each flow distribution plate, the installation of sensors and fabrication of the fuel call are simplified.Type: ApplicationFiled: March 31, 2003Publication date: May 13, 2004Inventors: Nariaki Kuriyama, Jun Sasahara, Tadahiro Kubota, Toshifumi Suzuki, Yuji Isogal, Sang-Joon John Lee

Publication number: 20040091765Abstract: In a fuel cell assembly comprising a plurality of cell each including an electrolyte layer (2), a pair of diffusion electrode layers (3, 4) interposing the electrolyte layer between them, and a pair of flow distribution plates (5) for defining passages (10, 11) for fuel and oxidant fluids that contact the diffusion electrode layers, the fuel cells are arranged on a common plane. Therefore, the vertical dimension of the fuel cell assembly can be minimized, and a fuel cell assembly of favorable electric properties can be achieved. Each flow distribution plate is typically formed with communication passages for communicating fluid passages defined on each side of the electrolyte layer at a prescribed pattern. The communication passages and through holes communicate the fluid passages in such a manner that adjacent fuels cells have opposite polarities.Type: ApplicationFiled: April 1, 2003Publication date: May 13, 2004Inventors: Sang-Joon John Lee, Jun Sasahara, Nariaki Kuriyama, Tadahiro Kubota, Toshifumi Suzuki, Friedrich B Prinz, Suk Won Cha, Amy Chang-Chien, Yaocheng Liu, Ryan O'hayre

Publication number: 20030199387Abstract: In a fuel cell comprising a tubular casing, an electrolyte layer received in the tubular casing, and a pair of gas diffusion electrodes interposing the electrolyte layer and defining a fuel gas passage and an oxidizing gas passage, respectively, each gas diffusion electrode is formed by stacking a plurality of layers of material therefor, for instance in the axial direction of the casing. Because the gas diffusion layers are formed layer by layer, components can be formed in highly fine patterns so that a highly compact tubular fuel cell can be achieved. Similarly, the dimensions of the various elements of the fuel cell can be controlled in a highly accurate manner. Also, the geometric arrangement can be changed at will in intermediate parts of each gas passage.Type: ApplicationFiled: June 2, 2003Publication date: October 23, 2003Applicants: Honda Giken Kogyo Kabushiki Kaisha, Stanford UniversityInventors: Yuji Saito, Jun Sasahara, Nariaki Kuriyama, Tadahiro Kubota, Toshifumi Suzuki, Yuji Isogai, Friedrich B.

Patent number: 6410835Abstract: Rhythm sensations can be represented in time to music by using the entire body and to create powerfulness and rhythm sensations. Stepping position indication data which is set by a rhythm setting section is read from a stepping position indication data memory, and the stepping position instruction contents are scrolled and displayed on a monitor by a scroll display control section, thereby performing instructions of the stepping position and the stepping operation timing. When the fact that a player steps on a step-on base section in accordance with the display contents of the monitor is detected by a cable switch and this is input from a stepping operation monitor section, a score proportional to the timing deviation is calculated by an amount-of-deviation detection/totaling section, and next, an evaluation is performed by the rhythm setting section. Then, the next stepping position indication data is set according to the evaluation result.Type: GrantFiled: February 1, 2001Date of Patent: June 25, 2002Assignee: Konami Co., Ltd.Inventors: Toshifumi Suzuki, Katsunori Okita, Kazuya Takahashi, Toru Takeda
