    摘要： The invention provides an electrolyte membrane that allows an operating temperature of a solid polymer membrane fuel cell to be raised and an operating temperature of a solid oxide fuel cell to be lowered. This electrolyte membrane can be used in a fuel cell that is operable in an intermediate temperature range. The invention also provides a fuel cell using such an electrolyte membrane. The electrolyte membrane has a hydrated electrolyte layer, and dense layers made of a hydrogen permeable material that are formed on both sides of this electrolyte layer. Both sides of the electrolyte membrane are coated with dense layers. Consequently, evaporation of moisture contained in the electrolyte layer is suppressed, and increase in the resistance of the membrane is inhibited. As a result, the range of the operating temperature of the fuel cell can be enlarged.

    摘要： A fuel cell having a single cell 20 comprises a hydrogen permeable metal layer 22 and a cathode 24 as layers equipped with catalytic metal for promoting a reaction of a labile substance supplied to the fuel cell during production of electricity in the fuel cell. Also, the fuel cell has an electrolyte layer 21 formed with a solid oxide. The electrolyte layer 21 has a high grain boundary density electrolyte layer 27, and low grain boundary density electrolyte layers 25 and 26 as decomposition reaction suppress parts to suppress a decomposition reaction of the solid oxide due to the catalyst metal.

    摘要： A fuel cell of the invention has a hydrogen permeable metal layer, which is formed on a plane of an electrolyte layer that has proton conductivity and includes a hydrogen permeable metal. The fuel cell includes a higher temperature zone and a lower temperature zone that has a lower temperature than the higher temperature zone. The hydrogen permeable metal layer includes a lower temperature area A corresponding to the lower temperature zone and a higher temperature area B corresponding to the higher temperature zone. The lower temperature area A and the higher temperature area B have different settings of composition and/or layout of components. This arrangement effectively prevents potential deterioration of cell performance due to an uneven distribution of internal temperature of the fuel cell including the hydrogen permeable metal layer.
