摘要:
The present invention provides a separating plate for a fuel cell stack and method of manufacturing the same, and more particularly, to a separating plate for a fuel cell stack and method of manufacturing the same, in which the separating plate constituting the fuel cell stack is formed in such a fashion as to interpose an array of metal pipes between two sheets of composite material, and a gasket abutting against the separating plate is formed in such a fashion as to define hydrogen and air flow channels, thereby removing a contact resistance between two adjoining separating plates constituting unit cells to improve the efficiency of the fuel cell.
摘要:
The present invention provides an end plate for fuel cell stack and a method for manufacturing an end plate, which can increase flexural rigidity per weight, and improve strain at break, and reduce heat transmission by applying hybrid core element having honeycomb and form structures to an end plate having sandwich structure combined to both end portions of a fuel cell stack.

The object of this invention is to provide a hybrid composite journal bearing which is constructed so that a composite liner is positioned on an inner surface of a metal housing having a circular cross-section, thus preventing a journal from being broken or damaged or seized to the bearing, due to friction between the metal or composite journal and the journal bearing. The hybrid composite journal bearing (210) includes a metal housing (211) which is secured on an outer surface thereof to a bearing system and has a circular cross-section. A composite liner (212) is laminated to an inner surface of the metal housing (211) with a uniform thickness so as to minimize friction between the journal bearing and a journal.

摘要:
The present, invention relates to a transdermal absorption preparation. The transdermal absorption preparation of the present invention comprises a drug-containing adhesive layer, a drug-protective layer and a release layer, wherein the drug-containing adhesive layer contains ropinirole or a salt thereof, rubber, an adhesion-imparting resin, an antioxidant, and a transdermal absorption promoter. Also, the present invention provides a transdermal absorption preparation comprising a drug-containing adhesive layer, a drug-protective layer, and a release layer, wherein the drug-containing adhesive layer contains ropinirole or a salt thereof, acrylic rubber, an anti-crystallisation agent, and a transdermal absorption promoter. When the transdermal absorption preparation of the present invention is used for the treatment of Parkinson's disease or restless leg syndrome, no side effect due to an increase in the initial drug concentration in blood occurs and the skin penetration effect of the drug is excellent.
