Abstract
An electrolyte layer () and a hydrogen-permeable metal layer () are fitted in a fitting portion () of a low thermal expansion member (), and a cathode electrode () is provided on the electrolyte layer (). Gas separators () are provided such that a low thermal expansion member () is held between the gas separators (). Since the low thermal expansion member () is made of metal which has a thermal expansion coefficient lower than that of the hydrogen-permeable metal layer (), thermal expansion of the hydrogen-permeable metal layer () can be suppressed. Accordingly, it is possible to reduce shear stress applied to an interface between the electrolyte layer () and the hydrogen-permeable metal layer () due to the thermal expansion. It is possible to suppress separation of the electrolyte layer () from the hydrogen-permeable metal layer () and occurrence of a crack in the electrolyte layer ().
