Publication number: 20220190353Abstract: The invention relates to the field of fuel cells, and in particular to a method for preparing highly stable catalyst coating slurry for fuel cells. The method for preparing highly stable catalyst coating slurry for fuel cells, includes at least two mixing and dispersing steps. The first mixing and dispersing step is carried out to mix and disperse the catalyst, perfluorosulfonic acid resin and solvent to obtain a first-stage mixed dispersion, and the other mixing and dispersing steps are carried out to mix and disperse the previous-stage mixed dispersion and the newly added perfluorosulfonic acid resin, wherein at least one mixing and dispersing step has a surfactant is added for mixing and dispersing. The catalyst in the catalyst slurry prepared by the method has good dispersion stability and less sedimentation, and good performance is achieved when the catalyst slurry is applied to membrane electrodes.Type: ApplicationFiled: February 17, 2022Publication date: June 16, 2022Applicant: SINOHYKEY TECHNOLOGY GUANGZHOU CO.

Patent number: 8904180Abstract: A key management system includes secured data stored on a first system secured by a control key stored securely on a key server. The secured data is secured against attacks such as unauthorized use, modification or access, where authorization to access the secured data is determined by knowledge of an access private key of an access key pair. When an authorized user is to access the secured data, the first system generates a request to the key server, signed with the access private key, wherein the request is for a decryption control key and the request includes a one-time public key of a key pair generated by the first system for the request. The first system can decrypt the decryption control key from the response, using a one-time private key. The first system can then decrypt the secured data with the decryption control key remaining secured in transport.Type: GrantFiled: October 16, 2012Date of Patent: December 2, 2014Assignee: CA, Inc.Inventors: Robert Allen, Robert A. Jerdonek, John Wang, Tom Wu

Patent number: 7943649Abstract: The invention encompasses novel compounds of Formula I or pharmaceutically acceptable salts thereof. These compounds are inhibitors of the microsomal prostaglandin E synthase-1 (mPGES-1) enzyme and are therefore useful to treat pain and/or inflammation from a variety of diseases or conditions, such as osteoarthritis, rheumatoid arthritis and acute or chronic pain. Methods of treating diseases or conditions mediated by the mPGES-1 enzyme and pharmaceutical compositions are also encompassed.Type: GrantFiled: October 24, 2008Date of Patent: May 17, 2011Assignee: Merck Frosst Canada Ltd.Inventors: Anh Chau, Bernard Cote, Yves Ducharme, Richard Frenette, Richard Friesen, Marc Gagnon, Andre Giroux, Evelyn Martins, Hongping Yu, Tom Wu
