  • Patent number: 10693153
    Abstract: An interconnector-electrochemical reaction unit cell composite body includes an electrochemical reaction unit cell and an interconnector. The interconnector has a plurality of combinations of protrusions protruding in the first direction and recesses provided on a side opposite the protrusions in the first direction and being concave toward the protrusions. At least one of the combinations is configured such that, as viewed in the first direction, the bottom of the recess is located on the side toward the open end of the recess. In a section parallel to the first direction, the recess is located within a width t2 of the protrusion in the second direction orthogonal to the first direction, and the width t1 of the recess in the second direction is smaller than the width t2.

  • Patent number: 9977374
    Abstract: A transfer unit includes a transfer target member, a first transfer device, and a holding member. The transfer target member has an image region to which an image is transferred and a non-image region to which the image is not transferred and which exists along an edge of the transfer target member. The transfer target member is transported in a path passing through a contact position where the transfer target member is brought into contact with an image holding body, which has a surface on which the image is held, so as to allow the image to be transferred to the transfer target member. The first transfer device transfers the image from the image holding body to the transfer target member. The holding member is brought into contact with the non-image region so as to hold the transfer target member without contact with the image region.

  • Publication number: 20180040906
    Abstract: In a fuel cell stack (1), a connection region SR in which a protrusion (67) of a current collecting plate (9) and a second output terminal (15) are electrically connected is formed within a belt-like range, namely, a connectable range SKH, between a first tangential line L1 tangential to the circumference of one through hole (10c) and a second tangential line L2 tangential to the circumference of the other through hole (10d). Therefore, since the flow of electric current generated in the fuel cell stack (1) is unlikely to be obstructed by the through holes (10), electric current is easily supplied to the second output terminal (15) from a current collecting section (65) of the current collecting plate (9) through the protrusion (67). As a result, a voltage loss is small, thereby improving the performance of the fuel cell stack (1).
