摘要： A fuel cell catalyst which has high power output characteristics and suppresses degradation of power generation performance due to starting, stopping or load variation; a manufacturing method thereof; a membrane electrode assembly for fuel cell; and a fuel cell including the same. The fuel cell catalyst includes at least catalytically active species and a carrier supporting the catalytically active species. The catalytically active species are at least one selected from the group consisting of platinum, a platinum alloy, and a core-shell catalyst in which a core of a metal different from platinum is coated with a shell containing platinum, the carrier is a carbon material, and at least one of the catalytically active species and the carrier contain(s) fluorine atoms.

摘要： Provided is a method for producing a difluorophosphate, which can simply and easily produce a high-purity difluorophosphate in an industrially advantageous manner. The method includes steps of: reacting an aqueous hydrofluoric acid solution with an oxyhalide of phosphorous (except phosphoric trifluoride) to produce a crude difluorophosphoric acid; reacting the crude difluorophosphoric acid with a halide of an alkali metal, an alkaline earth metal, aluminum or an onium to produce a difluorophosphate in the crude difluorophosphoric acid; and heating and drying the crude difluorophosphoric acid containing the difluorophosphate to distill away the crude difluorophosphoric acid, or precipitating the difluorophosphate in the crude difluorophosphoric acid by crystallization, subsequently separating the difluorophosphate by solid-liquid separation, and further distilling away the crude difluorophosphoric acid contained in the difluorophosphate after solid-liquid separation.

摘要： A non-aqueous electrolytic solution includes a phosphoric acid diester salt, which can suppress deterioration of charge-discharge characteristics of a power storage element, and can suppress the rise in internal resistance after storage at high temperature. The phosphoric acid diester salt is represented by the following chemical formula (1): in which Mn+ represents a hydrogen ion, an alkali metal ion, an alkali earth metal ion, an aluminum ion, a transition metal ion, or an onium ion, R1 and R2 are different from each other and represent a hydrocarbon group having 1 to 10 carbon atoms, or a hydrocarbon group having 1 to 10 carbon atoms and having at least one of a halogen atom, a heteroatom, and an unsaturated bond, and n represents a valence.

摘要： A nonaqueous electrolytic solution for a secondary battery exhibits excellent cycle characteristics even in high-temperature environments. The solution includes at least one of boric acid esters, acid anhydrides, cyclic carbonates having an unsaturated bond, cyclic carbonates having a halogen atom, cyclic sulfonic acid esters, and amines having an acetoacetyl group. A secondary battery having a positive electrode and a negative electrode makes use of this electrolytic solution.
