A battery is composed of a positive electrode in which a positive electrode active material layer including a positive electrode active material is formed on a positive electrode collector, a negative electrode in which a negative electrode active material layer including a negative electrode active material is formed on a negative electrode collector, a separator provided between the positive electrode and the negative electrode, and an electrolyte impregnated in the separator. The battery further includes at least one of a heteropoly acid and a heteropoly acid compound as an additive at least in one of the positive electrode, the negative electrode, the separator, and the electrolyte.

Non-aqueous electrolyte battery including an amorphous material

A nonaqueous electrolyte battery includes: a positive electrode; a negative electrode; a nonaqueous electrolyte that includes a solvent and an electrolyte salt, the solvent including a halogenated cyclic carbonate of the Formula (1) below, or at least one of unsaturated cyclic carbonates of the Formulae (2) and (3) below; and a polyacid and/or a polyacid compound contained in the battery,

An electrochemical energy generating apparatus with which the crossover of a fuel can be suppressed and a method of driving the apparatus are disclosed. The electrochemical energy generating apparatus (e.g., a fuel cell system) includes an electrochemical device (fuel cell) which has an electrolyte membraneclamped between opposed electrodes and which generates electrochemical energy by a reaction of an alcohol with water at one (fuel electrode) of the electrodes and a fuel evaporating section by which a fuel including said alcohol and substantially not containing water is supplied in a gaseous state to the side of the one of the electrodes of the electrochemical device. The method of driving the electrochemical energy generating apparatusincludes supplying the fuel in the gaseous state to the one of the electrodes by the fuel evaporating section.
