A dielectric film which has high electrical resistance and excellent durability and a process for producing the dielectric film are provided. Also provided is a transducer which has large displacement and excellent durability. The dielectric film includes a three-dimensional crosslinked body that is synthesized from an organic metal compound, a rubber polymer that is other than a polydimethyl siloxane and has a functional group that is reactive with the organic metal compound, and an inorganic filler that has a functional group that is reactive with the organic metal compound. The transducer is configured by interposing the dielectric film between at least a pair of electrodes. The dielectric film may be produced by preparing a first solution that contains a rubber polymer and an inorganic filler in a solvent that is capable of dissolving the rubber polymer and of chelating an organic metal compound, then preparing a second solution by mixing the organic metal compound into the first solution, and then removing the solvent from the second solution to allow a crosslinking reaction to proceed.

A shape and conductivity of a cylindrical porous metal substrate of low power collection losses are defined, and a solid oxide fuel cell of a high output or high start-up performance is provided by using the cylindrical porous metal substrate. In the solid oxide fuel cell of the invention, the cylindrical porous metal substrate which has a conductivity of 130 S/cm or more is used, and a power collecting section is connected to a position which does not exceed 100 cm from any place thereof. A first electrode, a solid electrolytic layer, and a second electrode are formed on a full periphery of the cylindrical porous metal substrate. Thus, it is possible to obtain a solid oxide fuel cell of easy cell formation and low power collection losses, i.e., high durability and a high output.

A combined cell structure for a solid oxide fuel cell includes a plurality of tube-type or flat-tube-type solid oxide fuel cells combined in series in a longitudinal direction. The combined cell structure includes first and second cells each having a first electrode, a second electrode and an electrolyte layer between the first and second electrodes. The combined cell structure further includes a support member connecting the cells. The support member can include a first sub-support member passing through a hollow portion of the first cell, and a second sub-support member passing through a hollow portion of the second cell. In the combined cell structure, one end of the first sub-support member is fixedly coupled to one end of the second sub-support member. Accordingly, the first and second cells are connected to each other in the direction of reactant flow.

A current collector includes a thin porous substrate and a hydrophilic material, where the hydrophilic material is provided to holes of the thin porous substrate or surfaces of skeleton elements of the porous substrate so that hydrophilic areas formed by the hydrophilic material successively pass through the thin porous substrate between both surfaces of the thin porous substrate. In the current collector, water is let out through the hydrophilic areas and does not stay on an interface between an electrode and the current collector so that reaction gas is not hampered and is supplied, unlike a conventional current collector. When the current collector is applied to a polymer electrolyte fuel cell, water is supplied with reliability through the hydrophilic areas to a polymer electrolyte membrane so that the polymer electrolyte membrane is effectively humidified. The current collector applied to a cathode achieves a profound effect because reaction product water tends to stay around a cathode of any types of fuel cells. The current collector also includes gas flow paths which are surrounded by particles of a hydrophobic material and pass through the thin porous substrate between both surfaces of the thin porous substrate. As a result, gas permeability of the current collector is maintained with reliability.
