Description of the Related Art As a distributed power source having a very high thermal efficiency of 40 to 60%, no noise or vibration, and no fear of air pollution, research and development have been actively conducted toward the practical use of fuel cells. As a fuel cell, a phosphoric acid type that operates at 150 to 230 ° C., a solid polymer type that operates at 100 ° C. or less,
There are an alkali type, a molten carbonate type that operates at 600 to 700 ° C., and a solid electrolyte type that operates at 800 to 1000 ° C. Any of these fuel cells can use hydrogen as a reactant. In addition, the catalyst such as platinum of the electrode is CO
Therefore, it is preferable that the CO concentration in the hydrogen-containing gas supplied to the fuel cell is as low as possible, and some of them are said to require 10 ppm or less. Therefore, in order to use hydrogen produced by the conventional steam reforming method of hydrocarbons or alcohols as a fuel gas for a fuel cell, crude hydrogen is further refined by a CO shift converter or a hydrogen purifier, and the CO content is 10 ppm. The following high purity is required, the process therefor is complicated, and a large amount of high-temperature heat energy is required, which is a problem in terms of cost.

No. 5,229,102 describes a reformer which selectively permeates generated hydrogen by supplying hydrocarbon to a tubular porous ceramic membrane filled with a catalyst. ing. As a result, by removing the generated hydrogen out of the system, the equilibrium of the reforming reaction leans toward the hydrogen producing system, resulting in 750
Whereas a high temperature of ~ 880 ° C was required, 300 ~ 7
It is described that the reforming can be performed at a relatively low temperature of 00 ° C. Further, since it is possible to perform reforming at a relatively low temperature, it is described that a temperature about the exhaust gas of a gas turbine or a gas engine can be used as a reforming heat source. Also, apart from this,
A technique is also known in which a palladium-based thin film is used in combination with a reforming device, hydrogen obtained by reforming is made into high-purity hydrogen through the thin film, and this is supplied to a fuel cell.
