Latest Patents

Kimura is credited with 1 patent: “Electroconductive Resin Composition and Separator for Fuel Cell.” The invention describes molding an electroconductive plate from a composition containing an electroconductive agent and a radical-polymerizable thermosetting resin system with an acid value within a specified range. Carbon powder is identified as a possible electroconductive agent, while the resin system may combine a radical-polymerizable resin with a radical-polymerizable diluent. The patent also describes preferred material properties, including a double-bond equivalent of about 200 to 1,000 for the resin and a glass-transition temperature of at least 120°C for the hardened product. It specifies an electroconductive-agent-to-resin-system weight ratio of about 55:45 to 95:5.
