Abstract: By a microbial fuel cell including: an anode electrode that includes, as a catalyst, current-generating bacteria supplied from soil or mud, and oxidizes an organic fuel supplied from soil or mud; and a cathode electrode that reduces oxygen supplied from air or water, the microbial fuel cell having an oxygen permeation restricting layer between the anode electrode and the cathode electrode facing each other, it is possible to provide, at low cost, a microbial fuel cell having high power generation performance due to direct power generation from soil or mud and capable of being thinned and miniaturized.

Abstract: In a mill having a first mill provided with a first grinding surface and a second mill provided with a second grinding surface, the first grinding surface includes a first groove in a curved shape which extends from a side of a center of rotation C toward an outer circumference, the second grinding surface includes a second groove in a curved shape which extends from the side of the center of rotation C toward the outer circumference, and while the first grinding surface and the second grinding surface are superimposed on each other, the first groove and the second groove are not superimposed on each other and an angle (an angle of intersection) β at which the first groove and the second groove intersect with each other is 10°≤β≤50°.
