Patent number: 8415072Abstract: A membrane electrode assembly for a fuel cell provides a current collector adjacent to an electrode catalyst layer. Since electrons passing between the current collector and the electrode catalyst layer do not pass through a diffusion layer or a supporting layer, the diffusion layer or supporting layer may be non-conductive. Thus, various materials that are hydrophilic, hydrophobic, porous, hydrous, or the like can be used for the diffusion layer and the supporting layer, thereby improving the performance of the fuel cell. In addition, manufacturing costs of the membrane electrode assembly can be decreased since the membrane electrode assembly can be manufactured quickly with low energy.Type: GrantFiled: August 23, 2006Date of Patent: April 9, 2013Assignee: Samsung SDI Co., Ltd.Inventors: Jung-min Oh, Hae-kyoung Kim, Ji-rae Kim, Joon-hee Kim, Yoon-hoi Lee, Sang-hoon Joo

Patent number: 7455345Abstract: The present invention relates to a sunshade apparatus for automobiles. In the apparatus, first and second linking rods, which function to stretch or close first and second arm units jointed to a shade bar, are actuated by first and second racks, which are engaged with motor-operated first and second drive pinions and are rectilinearly moved in opposite directions. Further, torsion springs are fitted over respective pivots, which joint the upper arm members of the first and second arm units to the shade bar, such that the torsion springs can promote the stretching of respective upper arm members. The torsion springs can be easily assembled in the apparatus, do not generate vibration or noises, and are light, thus reducing the power required to move the shade bar upwards or downwards. Therefore, the present invention realizes the smallness of the drive unit and the lightness of the sunshade apparatus.Type: GrantFiled: December 12, 2007Date of Patent: November 25, 2008Assignee: Korea Fuel-Tech CorporationInventor: Joon Hee Kim
