  • Publication number: 20180287165
    Abstract: A secondary ionomer that enhances activity and stability of a cathode catalyst in a polymer electrolyte membrane fuel cell includes the ionic liquid, 1-methyl-2,3,4,6,7,8-hexahydro-1H-pyrimido[1,2-a]pyrimidin-9-ium 1,1,2,2,3,3,4,4,4-nonafluorobutane-1-sulfonate ([MTBD][C4F9SO3]). When contacting the catalyst, [MTBD][C4F9SO3] enhances catalyst activity and stability more effectively than previously known ionomers, likely by preventing oxide formation and water adsorption at the catalyst surface. The disclosed secondary ionomer is thus most effective when completely coating the catalyst.

  • Publication number: 20100049966
    Abstract: To prevent information leakage at the time of transferring secret information data stored by using secret sharing scheme to the outside. Data to be transferred to a delivery destination of secret information data is divided into a plurality of data pieces by using the secret sharing scheme, and a part of the data pieces is stored in a portable storage medium by a data delivery source and is delivered to the data delivery destination by means such as a package delivery service. A computer at the data delivery destination accesses a predetermined website to download the other data pieces. A computer at the data delivery destination restores the original secret information data from the data pieces obtained via such two kinds of routes.
