Provided is an active material for a fluoride-ion secondary battery, the active material containing a composite fluoride. The composite fluoride has a layered structure and is represented by a composition formula AMF, where A is an alkali metal, M is a transition metal, 0&#x3c;m&#x2264;2, 1&#x2264;n&#x2264;2, and 3&#x2264;x&#x2264;4. The alkali metal may be at least one kind selected from the group consisting of Na, K, Rb, and Cs. The transition metal may be a 3transition metal.

A high-temperature operation fuel cell system includes a cell stack; a reformer; a raw material supplier supplying a raw material to the reformer; a water supplier supplying reforming water; an air supplier supplying electric power generation air; a combustion chamber in which an off-gas from the cell stack is combusted and which heats the cell stack and the reformer; an igniter igniting the off-gas in the combustion chamber; and a controller. In a start-up sequence, the controller controls so that the raw material is supplied to the reformer, the electric power generation air is supplied to the cell stack, the off-gas is ignited by the igniter, and after the ignition, the supply of the reforming water is started, and after the supply of the reforming water is started, the controller further controls the air supplier to increase the flow rate of the electric power generation air in a stepwise manner.

A desulfurization apparatus according to the present invention includes: a first desulfurizer filled with a first desulfurization agent that removes a first sulfur compound from a hydrocarbon fuel; and a second desulfurizer filled with a second desulfurization agent that removes a second sulfur compound from the hydrocarbon fuel, the second desulfurizer being provided downstream of the first desulfurizer in a flow direction of the hydrocarbon fuel. The second desulfurization agent is constituted by a porous coordination polymer having a polymeric structure that is a combination of copper ions and organic ligands. A sulfur compound adsorption ability of the second desulfurization agent to adsorb the second sulfur compound is different from a sulfur compound adsorption ability of the first desulfurization agent to adsorb the first sulfur compound. A temperature of the second desulfurization agent is kept to 100&#xb0; C. or lower. The desulfurization apparatus thus configured makes it possible to efficiently remove the sulfur compounds from the hydrocarbon fuel at low cost with a simple configuration.
