Patent number: 9118044Abstract: A method for manufacturing a manifold for a fuel cell with a multilayer structure by injection-molding individual manifolds, each having welding projections and welding guides, and bonding the injection-molded individual manifolds by vibration welding includes arranging welding projections of an upper individual manifold and welding guides of a lower individual manifold to be engaged with each other while maintaining a uniform gap between each other to bond a plurality of individual manifolds in an up and down stacking structure, pressing the lower individual manifold upward, and applying vibration to the upper individual manifold in the left and right direction, thus bonding the upper and lower individual manifolds. Among the welding projections of the upper individual manifold, a non-horizontal welding projection whose longitudinal direction does not coincide with the vibration direction of the individual manifold has a variable height.Type: GrantFiled: May 1, 2013Date of Patent: August 25, 2015Assignees: HYUNDAI MOTOR COMPANY, Kia Motors Corporation, Wooshin Industrial Co., Ltd.Inventors: Duck Whan Kim, Sae Hoon Kim, Young Bum Kum, Young Tae Kim, Chang Jun Lee

Patent number: 8938955Abstract: An exhaust manifold includes: an inlet portion which collects exhaust gas discharged through a first to a fourth exhaust ports; an outlet portion discharging the exhaust gas; and a tube portion connecting the inlet and the outlet portions. The inlet portion comprises: a first inlet portion one end of which communicates with the first and the second exhaust ports; and a second inlet portion one end of which communicates with the third and the fourth exhaust ports. Since the inlet portion is provided as two considering the combustion sequence, the productability and the economic feasibility can be enhanced, and the surrounding space can be enlarged to enhance the workability, and a simple exterior appearance can be obtained, and interference between exhaust gases can be effectively prevented, and since the size of the exhaust manifold can be increased, an engine load can be reduced to improve the fuel mileage.Type: GrantFiled: May 23, 2011Date of Patent: January 27, 2015Assignee: Wooshin Industrial Co., Ltd.Inventors: Young Tae Kim, Kwang Hee Nam, Chun Ho Baek, Dong Kyu Lee

Patent number: 8900437Abstract: Disclosed is an apparatus and method for forming an oxidation layer on a manifold block for a fuel cell stack, which forms an oxidation layer uniformly over the entire surface of a long and complicated internal flow field of a manifold block. In particular, the apparatus for forming an oxidation layer on a manifold block for a fuel cell stack includes: an electrolyte bath which contains an electrolyte required for the formation of the oxidation layer, an electrode for supplying a required electron flow for the formation of the oxidation layer from a power supply to the manifold block immersed in the electrolyte of the electrolyte bath and to the electrolyte, and an air supply for supplying oxygen to the electrolyte. Even more particularly, the electrode connected to the electrolyte is inserted into each internal flow field of the manifold block to provide an effective electron flow therein.Type: GrantFiled: November 22, 2011Date of Patent: December 2, 2014Assignees: Hyundai Motor Company, Kia Motors Corporation, Wooshin Industrial Co., Ltd.Inventors: Duck Whan Kim, Young Bum Kum, Sae Hoon Kim, Jung Han Yu, Chang Jun Lee, Young Hwan Ko
