  "textContent": "A membrane-electrode assembly that has high heat resistance and chemical resistance and moreover can function stably even at high temperature, the membrane-electrode assembly being made by joining gas diffusion electrodes to both faces of a proton-conductive membrane, and being characterized in that membrane-electrode joining parts where the proton-conductive membrane and the gas diffusion electrodes are joined together contain a three-dimensionally crosslinked structure that comprises metal-oxygen bonds and is formed through a sol-gel reaction; a membrane-electrode assembly as described above, characterized in that the gas diffusion electrodes have a precious metal catalyst supported on surfaces thereof in advance, or a membrane-electrode assembly as described above, characterized in that the membrane-electrode joining parts further contain carbon fine particles having a precious metal catalyst supported thereon, in addition to the three-dimensionally crosslinked structure; methods of manufacturing these membrane-electrode assemblies; and a polymer electrolyte fuel cell or direct methanol type fuel cell that uses such a membrane-electrode assembly and hence can cope with high-temperature operation.",
