Membrane-electrode assembly for fuel cell, manufacturing method thereof, and solid polymer fuel cell using membrane-electrode assembly

By layering a gas expansion layer, which has a first conductive layer comprising a specific conductive carbon material and a specific high molecular weight polymer, on a catalyst layer in such a way that the catalyst layer and the first conductive layer are in contact and the high molecular weight polymer in the first conductive layer is present with greater density at the surface in contact with the catalyst layer than at the surface not in contact with the catalyst layer, it is possible to provide a membrane-electrode assembly having strong adhesion between the catalyst layer and gas expansion layer. In addition, by further employing a gas expansion layer, which has a second conductive layer comprising a specific conductive carbon material and a specific high molecular weight polymer, on the first conductive layer and layering the gas expansion layer on the catalyst layer in such a way that the high molecular weight polymer in the first conductive layer is present with greater density at the surface in contact with the catalyst layer than at the surface in contact with the second conductive layer and the high molecular weight polymer in the second conductive layer is present with greater density at the surface in contact with the first conductive layer than at the surface not in contact with the first conductive layer, it is possible to provide a membrane-electrode assembly for a fuel cell that suppresses positional offset between the catalyst layer and a conductive porous layer and between the conductive porous layer and a conductive porous base material.

Inspecting device

The invention provides an inspecting device. The inspecting device is provided with a moving part, a pressing part, a positioning part, a declining part and a rising part. The moving part can move between an inspecting position for inspecting a substrate and a loading and unloading position for loading and unloading the substrate. The pressing part goes down from the upper side of the moving part which is on the inspecting position to a declining position, and presses the substrate to the moving part. When the pressing part presses the substrate to the moving part, the positioning part positions the moving part at least in the moving direction relative to the pressing part. When the moving part is on the inspecting position, the declining part goes down from the upper side of the inspecting position independently relative to the pressing part on the declining position. The declining part is provided with a first contact part, and the first contact part is electrically contacted with a first contacted part arranged on the upper surface of the substrate. When the moving part is on the inspecting position, the rising part rises from the lower side of the inspecting position independently relative to the pressing part on the declining position. The rising part is provided with a second contact part, and the second contact part is electrically contacted with a second contacted part arranged on the lower surface of the substrate.
