  • Patent number: 10325726
    Abstract: A multilayer ceramic capacitor includes a laminated body and first and second external electrodes respectively on both end surfaces of the laminated body. When regions where first internal electrodes or second internal electrodes are not present are regarded as side margin portions in a cross section of the laminated body as viewed from the laminating direction, the side margin portions include multiple side margin layers, and the content of Si in the side margin layer closest to the internal electrode is lower than that in the side margin layer other than the side margin layer closest to the internal electrode.
    Type: Grant

  • Patent number: 9812260
    Abstract: A multilayer ceramic capacitor includes a ceramic body and external electrodes provided on opposite end surfaces of the ceramic body. The ceramic body includes an inner layer portion including a plurality of ceramic layers defining inner layers and a plurality of first and second internal electrodes each disposed at an interface of adjacent ones of the ceramic layers defining the inner layers, outer layer portions sandwiching the inner layer portion in a direction in which the layers are stacked, and side margin portions sandwiching the inner layer portion and the outer layer portions in a widthwise direction. The side margin portion includes pores that decrease in number along a direction from inside to outside of the ceramic body.

  • Patent number: 9673458
    Abstract: A fuel cell includes a membrane electrode assembly, a separator, a fluid channel, a fluid manifold, a plurality of protruding elastic members, and a plurality of sealing members. A fluid is to flow in a stacking direction through the fluid manifold. A connection channel is provided between the plurality of protruding elastic members to connect the fluid channel and the fluid manifold. The plurality of sealing members are provided adjacent to the plurality of protruding elastic members in the stacking direction and extend in a direction to cross a flow direction in which the fluid flows along the connection channel. Each of the plurality of protruding elastic members has overlapping regions that overlap the plurality of sealing members as seen from the stacking direction. The overlapping regions are separated from each other in the flow direction.
