Abstract: To provide a thermoelectric conversion material having an enhanced thermoelectromotive force and a production method thereof. A thermoelectric conversion material including a matrix and a barrier material, wherein the matrix contains Mg2Si1-xSnx (x is from 0.50 to 0.80) and an n-type dopant and the barrier material contains Mg2Si1-ySny (y is from 0 to 0.30), and a production method thereof. A thermoelectric conversion material and a production method thereof, in which the movement of minority carrier is blocked by a barrier material and the thermoelectromotive force is thereby enhanced, can be provided.

Abstract: A catalyst layer for a fuel cell, wherein the catalyst layer comprises a catalyst-supporting carbon and an ionomer; wherein, in a particle size distribution obtained by the laser diffraction/scattering method, the catalyst-supporting carbon has at least two aggregate particle size peaks at less than 1 μm and at 1 μm or more; wherein, when a thickness of the catalyst layer is divided into three equal parts, the catalyst layer has a first region on a gas diffusion layer side, a second region in a middle part, and a third region on an electrolyte membrane side; and wherein a void ratio VG of the first region is 5% or more higher than a void ratio VM of the third region.
