摘要： A membrane-electrode structure having an electrode catalyst layer adhered to a diffusion electrode, wherein the structure is manufactured by applying a catalyst paste onto a sheet substrate, and then dried to form a plurality of electrode catalyst layers. The electrode catalyst layers are thermally transferred onto each side of a polymer electrolyte membrane to form a laminated body. A first slurry is applied on a carbon substrate layer, and dried to form a water-repellent layer, and then, a second slurry is applied on the water-repellent layer, and dried to form a hydrophilic layer to form a diffusion electrode. The diffusion electrode is then laminated on the electrode catalyst layer through the hydrophilic layer, and then pressed under heating to integrate the laminated body and the diffusion electrode.

摘要： After placing inside a reactor second container a substrate to which a CNT not yet carrying a catalyst is adhered under a sealed environment of supercritical carbon dioxide through which a Pt catalyst complex is dispersed, a temperature of the supercritical carbon dioxide is maintained below a decomposition temperature of the Pt catalyst complex, and a temperature of the CNT not yet carrying a catalyst is maintained at or above the decomposition temperature of the Pt catalyst complex by heating the substrate. Further, a pressure of the supercritical carbon dioxide is maintained at 7.5 MPa, which is slightly higher than a supercritical pressure (7.38 MPa) of carbon dioxide. The supercritical carbon dioxide is then caused to contact the CNT adhered to the substrate, and as a result, a Pt catalyst is carried on the CNT.
