In an engine system with a reformer being installed in an exhaust pipe to reform a fuel, a control valve for controlling a flow rate of exhaust gas is provided downstream from an installed position of the reformer in the exhaust pipe. In the engine system with the reformer, since a part of the exhaust gas can be trapped in a space between the reformer and an engine chamber by closing the control valve during an exhaust stroke, the reforming efficiency of the reformer can be heightened.

An object of the invention is to provide a catalyst of high activity having a dehydrogenation function or hydrogenation function, to provide a fuel cell with a high output density, and further to provide a hydrogen storage/supply device, with which hydrogen is stored or supplied in a high efficient manner.In order to achieve the above object, a porous oxide film of a metal oxide is formed on a hydrogen separation membrane surface of a catalyst having a dehydrogenation function or hydrogenation function and the hydrogen separation membrane is arranged so as to be partially exposed to at the interface with the porous oxide film. In doing so, hydrogen generated on the catalyst can quickly diffuse into the hydrogen separation membrane thereby efficiently releasing the hydrogen to outside of the reaction system. Eventually, the reaction efficiency can be improved. As to the fuel cell of the invention, the catalyst having the dehydrogenation function or hydrogenation function is used in a fuel cell and further in a hydrogen storage/supply device.

A proton-conductive composite electrolyte membrane, for a fuel cell, comprises a metal-oxide hydrate with proton conductivity and organic macromolecules in which an intermediate layer is formed between the metal-oxide hydrate and the first organic macromolecular electrolyte. The intermediate layer can enhance the adhesion at an interface between the metal-oxide hydrate and the organic macromolecule, and thereby the amount of methanol that penetrates along the interface can be reduced. Accordingly, the composite electrolyte membrane has both high proton conductivity and low methanol permeability, and a membrane electrode assembly that comprises the composite electrolyte membrane can produce a high output.

A dehydrogenation fuel theft prevention system for preventing the theft of dehydrogenation organic fuel containing hydrogen is provided. The dehydrogenation fuel theft prevention system is for systems including a reformer for dehydrogenating organic fuel containing at least hydrogen and a dehydrogenation fuel recovery tank for storing dehydrogenation fuel produced when organic fuel is dehydrogenated in the reformer. The theft prevention system is provided with a means for mixing an odorant as a component with a pungent odor other than the fuel components or a agent for coagulating the fuel components. The odorant or the coagulating agent is mixed when fuel is manufactured, distributed, utilized, recovered, or stored or fuel is about to be stolen.
