    摘要： This electrode catalyst layer for fuel cells is provided with: an electrode catalyst that comprises a conductive carrier and platinum-containing metal particles supported on the surface of the conductive carrier; and an ionomer that covers the electrode catalyst. This electrode catalyst layer for fuel cells is characterized in that the average thickness of the ionomer is 2.4 nm or less. This electrode catalyst layer for fuel cells is capable of having a good balance between proton transport properties and transport properties for a gas such as an oxidant gas or a fuel gas even in cases where the amount of supported platinum is decreased. In addition, an electrode for fuel cells, a membrane electrode assembly for fuel cells, and a fuel cell, each having good current-voltage characteristics, can be obtained using the above-described electrode catalyst layer for fuel cells.

    摘要： Provided is an electrocatalyst for solid polymer fuel cells capable of increasing the active surface area for reactions in a catalyst component, increasing the utilization efficiency of the catalyst, and reducing the amount of expensive precious metal catalyst used. Also provided are a membrane electrode assembly that uses this electrocatalyst and a solid polymer fuel cell. An electrocatalyst for a solid polymer fuel cell is provided with a catalyst and solid proton conducting material. A liquid conductive material retention part that retains a liquid proton conducting material that connects the catalyst and solid proton conducting material is provided between the same. The surface area of the catalyst exposed within the liquid conductive material retention part is larger than the surface area of the catalyst in contact with the solid proton conducting material.
