Claim Text:
1. A fuel cell apparatus comprising: a fuel cell stack in which an end plate is arranged at both ends of a cell stacked body that includes a plurality of stacked single cells; a conduit that is bolted to the end plate of the fuel cell stack, and that supplies and discharges fluid to and from the fuel cell stack; and a flange connecting the conduit to the end plate, wherein a stacked body internal manifold that is a flow path for the fluid and is provided extending through the cell stacked body is formed inside the cell stacked body; an end plate internal manifold that is communicated with the stacked body internal manifold and that extends in a direction that is at an angle inclined with respect to a direction in which the stacked body internal manifold extends is formed inside the end plate; a conduit internal flow path that is connected to the end plate internal manifold is formed inside the conduit; a portion of the conduit internal flow path that includes a connecting portion that connects to the end plate is such that a direction in which the portion extends is inclined in the same direction as the direction in which the end plate internal manifold is inclined, with respect to a direction perpendicular to a surface of the end plate; a surface of the flange that contacts the end plate is formed perpendicular to the conduit internal flow path near the portion that connects to the end plate; the end plate includes one or more bolt holes into which a respective bolt for connecting the flange to the end date is fitted; and each of the one or more bolt holes extends along an axis that is parallel to the direction in which the end plate internal manifold extends.
