    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.

    摘要： A lithium secondary battery employing as its negative electrode active material a material that increases in volume by alloying with lithium during charge achieves high discharge capacity and good cycle performance. The lithium secondary battery includes a negative electrode having a negative electrode active material (2) and a negative electrode current collector, a positive electrode having a positive electrode active material (1) and a positive electrode current collector (3), and a non-aqueous electrolyte. The negative electrode active material (2) is a material that increases in volume by alloying with lithium during charge. The negative electrode active material (1) is arranged so as to be on, and in contact with, the negative electrode current collector. The negative electrode active material (2) contains, when in an end-of-discharge condition, 8% or more of lithium with respect to the total capacity of the negative electrode active material (2) as measured when it does not contain lithium.
