Title: Membrane-electrode assembly and its manufacturing method
Inventor: SUGIURA MIKIO
IPC: H01M4/86
Filed: 2007-11-26
Abstract: <P>PROBLEM TO BE SOLVED: To provide a membrane-electrode assembly capable of preventing transfer of a catalyst in an electrode to an electrolyte membrane.  <P>SOLUTION: The membrane-electrode assembly has: an electrolyte membrane 1; a set of catalyst layers 4, 5 interposing the electrolyte membrane 1 from both sides; and diffusion preventing members 2, 3 made of a hydrocarbon ion exchange resin material, interposed between at least one of the catalyst layers 4, 5 and the electrolyte membrane 1. The diffusion and transfer of the catalyst can be prevented by interposing the diffusion preventing member formed with the hydrocarbon ion exchange resin material between the catalyst layer and the electrolyte membrane, based on such knowledge that in the process diffusing to the electrolyte membrane of Pt ions generated in the catalyst layer, the diffusion is suppressed by the hydrocarbon ion exchange resin material. Since the diffusion preventing member is formed with the ion exchange resin material, cell reaction is not obstructed. Since the diffusion preventing member is formed with the ion exchange resin material, substitution of part of existing electrolyte membrane is made possible so as not to exert large influence upon cell performance.  <P>COPYRIGHT: (C)2009,JPO&INPIT

Filed: 2007-11-26
Abstract: <P>PROBLEM TO BE SOLVED: To make it possible to determine whether or not there is difference between discharge speeds of large droplets and small droplets having different volumes discharged from the same nozzle in a recording head.  <P>SOLUTION: A large droplet gathering pattern POD with a matrix shape is formed ((A) in the figure) by the nozzles of nozzles of the respective nozzle rows (K1, K2, C, M, Y) while scanning the recording head in a Y direction. Then, a small droplet gathering pattern PKD is formed adjacent to the finish end of the large droplet gathering pattern POD in the Y direction. There is almost no gap between the finish end of the large droplet gathering pattern POD and the start end of the small droplet gathering pattern PKD when the discharge speeds of the large droplets and the small droplets are substantially the same ((B) in the figure). Landing position is shifted in the scanning direction, and thereby the gap H2a is formed ((C) in the figure), when the discharge speed of the small droplets is slow. Consequently, it can be determined that there is the difference between the discharge speeds of the large droplets and the small droplets.  <P>COPYRIGHT: (C)2009,JPO&INPIT
